Fuel Quality is Changing and Contaminates are Increasing:How to protect your gas fired turbine engine

Kristen Cassels - SGS North America, Inc.

Today’s highly efficient turbines rely on high-quality alloys to permit increased firing temperatures to be achieved and to maintain acceptable product life. Therefore more attention has to be placed on the quality of the fluids, from all sources, entering the gas turbine, especially the fuel. Gas Turbines can - and do - use a wide range of gaseous and liquid fuels and the subject of fuel quality is a major topic to consider in more depth.   As new gas fields are developed in remote sections of the globe, we at SGS have witnessed an accelerated development and production of gas fuels and especially the production of green gas fuels such as sour gas and land fill gases.   All Gas Turbine OEMs, including Siemens, provide comprehensive specifications covering the fuel quality permitted for use in a gas turbine. These are used to ensure fuel quality is defined at the onset of a project and throughout the lifetime of the turbine and are prepared to ensure acceptable turbine operation is achieved with little or no impact on major turbine component life.   At SGS we want to provide insight and understanding of fuel composition so that measures can be taken to minimize the impact of any major constituents of the fuel, along with the potential impact on turbine components of any identified contaminants and ways to mitigate this impact. Compositions of gaseous fuels, for example, can vary quite widely depending on their source and can contain a number of hydrocarbon species along with inert gases as well as contaminants. Liquid fuels are also commonly used, often as a back-up fuel, and these can also contain potentially harmful contaminants.

Microwave digestion replaces 10 hour ash methods for metals analysis in petroleum products

Reynhardt Klopper - Anton Paar, USA Inc.

Laboratories preparing petroleum samples for metals analysis have been using ASTM test methods D5708-B, D5863-A or IP 501 to prepare samples. These methods are slow, inefficient and laborious. Recently approved ASTM standard practice D7876 can reduce the preparation time, acid consumption and eliminate operator’s exposure to corrosive vapors. A novel microwave digestion instrument will be presented, which enables efficient and reproducible digestion of a wide variety of petroleum samples. Up to 24 different samples can be processed simultaneously, even applying varying acid mixtures. Digestions are performed under reflux or stirring to overcome challenges associated with highly viscous, buoyant, or reactive samples

The Analysis of contaminants in Petroleum Products

Michael Pohl - HORIBA Instruments, Inc.

Both organic, inorganic and organo-metallic compounds show up as contaminants in petroleum products.  They can range from ppb levels all of the way to wt.% in samples.  In crude oil these materials are contaminants which came through the sample treatment while in lubricating oils.  These are materials which were intentionally added for performance reasons.  These materials can include most every element in the Periodic Table with many occurring in the same sample.  These challenges require the use of multiple analytical techniques to solve these problems.

One of the most versatile ways to meet this challenge is to use X-ray Fluorescence Spectroscopy.  The two possible approaches, WDXRF and EDXRF, have evolved to be two possible solutions to this challenge.  Both techniques can handle multiple elements and have been developed to have reasonably LOQ types of values.  These approaches will be compared and contrasted using some real world samples for comparison. The application to actual samples from an application perspective will be made.

The Analysis of Regulated Phthalates in a Complex Matrix using Thermal Desorption-GC/MS

Rojin Belganeh - Frontier Lab
Terry Ramus - Diablo Analytical
Itsuko Iwai - Frontier Laboratories
Robert Freeman - Frontier Laboratories

Phthalates have been used as additives in plastic for many years to make them more flexible.  Several phthalates are regulated on a global scale, and several analytical techniques can be used for phthalates analysis.  Thermal Desorption (TD)-GC/MS is one of the easiest and most accurate methods for phthalate analysis. Recently manufacturers have switched formulations to include unregulated phthalates. Generally, phthalates are identified using both retention time and MS spectra. However, some unregulated phthalates have similar retention times and MS spectra, compared to regulated phthalates. This is the basis of existing ASTM and IEC methods for regulated phthalates by this technique.

Analysis, Characterization, and Deformulation of Apparently Similar Rubber Parts Using Multiple Modes of Pyrolysis-GC/MS

Terry Ramus - Diablo Analytical

The formulation details of the polymer parts are often not known to the manufacturer or other steps in the supply chain.  The same part number in the supply chain can result in a polymer part that is not made with the same formulation, yet the apparent polymer properties seem to be equivalent. Pyrolysis-GC/MS is used in multiple modes to characterize a set of rubber parts that seem approximately similar.  The results reveal significant differences in chemical composition.  Results can be used to monitor parts quality at the manufacturing point in the supply chain to reduce future variability in part failure.

Analysis of Acrylic Adhesives Using Pyrolysis-GC/MS

Itsuko Iwai - Frontier Lab
Terry Ramus - Diablo Analytical
Rojin Belganeh - Frontier Laboratories
Robert Freeman - Frontier Laboratories

Dicing tape is a backing tape used during silicon wafer dicing. The adhesive on the tape holds silicon dies, the pieces of semiconductor wafer, with high adhesion. The adhesive should include two features; the die must be held tightly during the cutting process, and the dicing tape must be easily removed after cutting. Die manufacturers seek techniques for material characterization of the dicing tapes as the compositions of adhesives are often not disclosed. This work demonstrates how to qualify and quantify the composition of dicing tapes using the multi-mode Pyrolysis GCMS while the adhesive was directly analyzed without sample preparation.

Novel Quantitation Method Development for Asphaltene Inhibitor Analysis Using Pyrolysis GC-MS and MS/MS

Lei (Lyla) Cheng - Ecolab
Tim Bonner - Ecolab
Christopher Durnell - Ecolab
Casado-Rivera Emerilis - Ecolab

Asphaltene inhibitors (AI) are polymer additives to prevent the aggregation of asphaltene molecules and therefore shift the asphaltene onset pressure. AI residual analysis is significant to understand the performance of AI. AI product A is dosed at very low concentrations into the oil (up to a few hundred parts per million by volume). The challenge is to improve sensitivity at low detection limit while a trace amount of sample is used by pyrolysis GC-MS. To solve this challenge, an improved pyrolysis GC-MS (selected ion monitoring, SIM) technique is being developed for the quantitation and the potential MRM (multiple reaction monitoring) method with higher sensitivity was investigated. The curve is linear ranging from 100 ppm to 1000 ppm. The SIM method has higher sensitivity than the Full scan and EIC method in the published patent method. MRM is still under development by investigating the characteristic fragment ions of the series of nonylphenol ions. This novel method has high repeatability and high sensitivity with small amount of sample use about 0.1~0.2 mg. The technique is going to be applied to monitor the performance of the AI product in filed.

50 Minute Detailed Hydrocarbon Analysis of Gasoline Using Gas Chromatography – Vacuum Ultraviolet Absorption Spectroscopy

James Diekmann - VUV Analytics
Jack Cochran - VUV Analytics

Detailed Hydrocarbon Analysis (DHA) by ASTM Method D6730 uses high-resolution GC-FID to separate and quantify individual spark-engine fuel compounds, which can then be reported as paraffins, isoparaffins, olefins, naphthenes, and aromatics (PIONA).  GC run time is long and post-processing data review is necessary to ensure accurate peak integration for closely eluting compounds.   GC with vacuum ultraviolet (VUV) absorption spectroscopy offers a new DHA approach.  VUV spectra uniqueness enables deconvolution while class similarity of spectra permits PIONA reporting.  DHA GC run time can be shortened to 50 min.  Fully automated data processing produces a compound and class report in 90 sec.

Olefin Class Characterization In Gasoline-Range Samples Using Gas Chromatography - Vacuum Ultraviolet Spectroscopy

Alex Hodgson - VUV Analytics
Jack Cochran - VUV Analytics

Olefins cause problems for refineries. For example, conjugated dienes in fluid catalytic cracking gasolines are prone to polymerization, which can plug downstream processes.   Gas chromatography with flame ionization detection or mass spectrometry struggles with olefin differentiation.  Methods specific for conjugated diene characterization vary in complexity, analysis time, and accuracy. Diene analysis using maleic anhydride addition takes more than 3 hours, and suffers from incomplete reactions and interferences.   Vacuum ultraviolet spectroscopy (VUV) differentiates gasoline hydrocarbons based on their distinctive spectra.  Olefins – and particularly conjugated dienes – absorb strongly in the higher wavelength region, allowing for deconvolution and quantitation in complex fuel matrices.

Corrosion control and chemically inert nanocoatings for use in the refining, petrochemical and analytical equipment industries.

Gary Barone - SilcoTek Corporation

pdf icon Download the presentation

Faced with growing demand to increase performance and lower costs, the refining, petrochemical, oil and gas industries are long overdue for new corrosion resistant coating technology that is more easily integrated into production. This paper will discuss silicon-based chemical vapor deposition (CVD) nanocoatings that, when applied to stainless steel and other alloys, are proven to cut maintenance costs by offering corrosion protection equivalent to exotic metals while also easing design, fabrication, and installation of coated parts.

By using a gas-phase CVD process, components with complex geometries or narrow passageways such as valves, fasteners, tubing and filters can be thoroughly treated both internally and externally.  The coating is molecularly bound to the base substrate, giving durability and flexibility without flaking, while the thin profile (approximately 1µm thickness) has no impact on design tolerances.  The silicon-based CVD coating’s performance is not directly related to thickness; rather, its advanced surface chemistry is extremely inert, greatly hindering corrosive interaction with the surface.

The coatings are tailored to provide specific high-performance properties that complement their corrosion resistance, including hydrophobicity, oxidation protection above 1000° C, and coking/fouling resistance.  The coatings’ versatility makes them ideal solutions throughout the refinery, not to mention exploration and upstream applications.  Silicon-based CVD coatings on stainless steel are cost-effective alternatives to duplex, super duplex and super alloys that offer a myriad of additional benefits for boosting output while decreasing maintenance-related costs.  Here, the silicon-based CVD coatings' material properties and corrosion performance will be examined and compared to alternative solutions.

Exposure results will be demonstrated for Salt Spray, ASTM G85; Immersion, ASTM G31, in Hydrochloric acid, bleach and sulfuric acid; Pitting and crevice corrosion, ASTM G48B; and impact on Galvanic corrosion between 6061 Aluminum and stainless steel.

Transferring Routine Lab GC Analysis to Automatic On-Line Measurement

Ulrich Gokeler - Siemens Industry, Inc.

Most industrial plants have analytical laboratories for off-line analysis. Depending on the process and task the objective is to support product quality and process trouble shooting. However, there are analysis that are repetitively performed daily or several times a day. By transferring such routine lab analyses to an automatic and on-line measurement system, there can be significant cost savings associated with it. Furthermore, measurement point dependent, because higher measurement frequency and repeatable sample conditions possibly enables improved process and quality control. This presentation will discuss upfront considerations and the possible benefits of transferring laboratory GC measurements.

Importance of Analytical Technology Throughout the SABIC Value Chain

Christian Wold - SABIC

SABIC offers a very broad portfolio of polyolefin and engineering thermoplastic polymers and has competencies across the value chain of feedstock cracking, polymerization, material development and advanced final part design. In this presentation, the importance of analytical technology will be addressed from a technology and innovation perspective using examples throughout the value chain;   Liquid feedstock streams for steam cracking are very complex in nature and detailed knowledge of the compositions provided by ICP-MS and 2DGC techniques are crucial for optimization of the cracking operations while preventing fouling from coke and metals .   After cracking the slate consists of a variety of useful monomers, monitored by GC and used for further polymerization into polyolefins or engineering thermoplastics.   For polymer development, information on distributions are paramount and analytical chemists unravel data on branching, co-monomer distributions and molecular weight all relatable to final application performance.   Finally as a customer focused organization SABIC works to provide solutions and innovative analytical sciences are required in the phase of trials and implementation to ensure success.

Sulfur in Natural Gas

Mickey Wood - INFICON

Natural Gas is a naturally occurring gas mixture that contains fixed gases and light hydrocarbons. Natural gas is colorless and odorless, although it often contains trace amounts of sulfurs as impurities. While natural gas producers often want to remove impurities such as H2S (Hydrogen Sulfide) and COS (Carbonyl Sulfide), they will often introduce odorants into the gas mixture that can serve as leak indicators and warning agents. In the US, the odorant TBM (Tert-Butyl Mercaptan) is often added into the gas stream and THT (Tetrahydrothiophene) is a commonly added odorant in Europe. Precise and fast measurement of natural gas composition is critical for producers, gatherers, and natural gas manufacturers; this often includes the need for analyzing sulfurs and odorants. Micro GC Fusion configured with two channels is capable of analyzing sulfurs and odorants found in natural gas streams in less than 1 minute.

GCxGCxMS of Diesel: A Three-Dimensional Separation Approach

Frank Wang - Exxonmobil Research and Engineering Co.

Diesel, a complex hydrocarbon mixture, was examined using comprehensive two-dimensional gas chromatography (GCxGC) and a field ionization mass spectrometer (FIMS), which preferentially yields molecular ions, providing an extra dimension for component separation. Molecular ions collected at low mass resolution can be assigned an NM-class (Nominal Mass-class) value that does not completely express hydrogen deficiency.  In contrast to formulae and Z-class assignments that are possible from ultrahigh mass resolution, NM-class assignments are not unambiguous; however, the separation provided by GCxGC can result in coelution of components that differ in NM-class.  Hence, compounds that are unresolved by GCxGC separation can be resolved by FIMS provided they differ in mass.  This technique allows for easy, automated data processing, evaluation of coelution on quantitative analysis (e.g., using FID) and the identification of additional chemical species and structures. The development of GCxGCxMS creates new opportunities to improve the ability to determine hydrocarbon composition and structure in complex petroleum and refined petroleum products. We will demonstrate the power of the three-dimensional technology using diesel as an example.

Analysis of Gums and Distillation Residues of Gasoline for Increased Accuracy of Particulate Emissions Prediction

Justin Pletzke - General Motors
Emily Popp - General Motors
Alex Bonkowski - General Motors
Jessica McGahan - General Motors
Mark Winston-Galant - General Motors

Particulate Matter Index (PMI) is the current standard used in the automotive industry to predict particulate emissions from gasoline-fueled vehicles.  PMI takes the weight fraction, vapor pressure, and double bond equivalent (DBE) value of every component in the fuel into account, including paraffins, oxygenates, olefins, and aromatics.  However, particulate emissions are largely attributed to high boiling range, high DBE value olefins and aromatics.  To probe this discrepancy, gums and distillation residues of several gasoline samples were generated and analyzed by GC-TOF and AccuTOF-DART.  These results will be compared to PMI of the whole fuel and particulate emissions data to determine if identifying and quantifying every component of gasoline for PMI is the most rational approach.

Fatty ACid Methyl Ester in Fuels by GC-MS & GCxGC

Ramkumar Dhandapani - Phenomenex

Fatty Acid Methyl Esters (FAMEs) are a big threat in aviation fuels as well as in biofuels. Accurate quantitation and separation of cis trans, low and higher boiling FAMes is essential from quality control prespective as well as from a safety prespective. In the present work a ZB-FAME GC column is utilized to accurately characterize FAME in Fuels by GC MS. Traditional selectivity like a 100% Polyethyleneglycol phase may have few coelutions of FAME, while coupling ZB-Fame with Mass spec based detection priovides excellent separation of cis & trans FAME along with lower level detection. Traditional high cyano selectivity takes an hour to separate Cis/ trans FAMEs, while ZB-FAME can separate them within 11 min. This approach was also extended to 2D GC using ZB-Fame in the first dimension & a 5% phenyl selectivity in the second dimension to obtain orthogonal separation. Thus analysis of fuels by GC MS & GCxGC using  ZB-FAME  assures safety of aviation fuels.

Understanding conversion and selectivity of gas phase hydrocarbon processes is often enhanced by the application of on-line analytical measurements to observe the chemistry in near real-time so that the end-user of the data can more easily link “cause and effect.” The agility and power of liberating the technology affords end users a means to determine the conditions for optimum yield, assure process control, understand process upsets, and characterize unknown streams with urgency not possible by conventional means. On-line process gas chromatography (GC) applications are typically limited to packed column and isothermal oven technology. This presentation will describe the use of fast GC column technology as applied to process GC to gather the analytical information needed to better understand, optimize, and probe chemical problems. The results illustrate simplifying a GC method by combining multiple isothermal column trains into a fast GC unit thereby reducing method development time and improving peak resolution.

Turning up the heat on WAX GC columns without getting burned

Vanessa Abercrombie - Agilent Technologies
Daron Decker - Agilent Technologies

100 % polyethylene glycol (PEG) columns, also known as WAX columns, are used for a wide variety of applications, such as industrial chemicals and petrochemicals. Traditional WAX columns have a maximum temperature limit of 250 °C isothermal and 260 °C programmed due to issues with decreased thermal stability, reducing the potential applications range. The Agilent J&W DB-HeavyWAX has an extended temperature limit, up to 280 °C isothermal and 290 °C programmed and increased thermal stability, increasing injection-to-injection retention time reproducibility and column lifetime. The increased upper temperature limit allows for faster analysis while minimizing possibility of carryover sample to sample.

Latest Developments in Ionic Liquid Stationary Phase Technology

Leonard Sidisky - MilliporeSigma (Supelco)
Jamie Desorcie - MilliporeSigma
Greg Baney - MilliporeSigma
Kathy Kiefer - MilliporeSigma

Over the years, extensive evaluations of columns manufactured with ionic liquid stationary phases have occurred. Their main strength was discovered to be unique selectivity. This selectivity is made possible due to the various combinations of cations and anions that are available along with spacer groups used to prepare these germinal dicationic phases. Columns prepared with di- or tricationic phases have the ability to perform many of the same applications as columns made with polysiloxane polymer or polyethylene glycol stationary phases of similar polarity, but with slight elution order changes. Many times this results in increased resolution and/or shorter run times. This paper will compare and contrast the selectivity of the ionic liquids stationary phases with traditional phases of similar or like selectivity’s for applications with a variety of different sample types from a number of industries including petrochemical, pharmaceutical, environmental, food and beverage and flavor and fragrance.

Mei Mei - University of Houston- Center for Petroleum Geoche
Jeffery C. Wright - University of Houston- Center for Petroleum Geoche
Adry Bissada - University of Houston- Center for Petroleum Geoche

Sound petroleum-resource assessment requires determination of petroleum generation potential, oil-in-place, and molecular characterization of that oil. Traditionally, this has been done by RockEval pyrolysis and solvent-extraction with subsequent SARA/GC/GCMS analysis. Rotovap of extracts and SARA fractions results in loss of light ends and other fractionation problems. A new approach using the Frontier Laboratories’ thermovaporization-multishot pyrolyzer, interfaced with cryo-trapping and Agilent’s GC-FID-MSD system, was recently developed to measure and characterize evolved products. Unfortunately, complexity of these released analytes deterred customary molecular characterization. More recently, the problem was overcome by utilizing pyrolysis GC/MSMS system and our new whole-oil analysis method.

Estimating Particulate Matter Index for Gasoline with Fast Gas Chromatography – Vacuum Ultraviolet Spectroscopy

Jack Cochran - VUV Analytics
Sean Jameson - VUV Analytics
Dan Wispinski - VUV Analytics
James Diekmann - VUV Analytics

Particulate Matter Index (PMI) indicates how fuel quality contributes to particle number emissions in automobiles.  Because gasoline is complex, GC-FID detailed hydrocarbon analysis (DHA) is used to separate and quantify individual compounds, followed by calculation of their contributions to the PMI.  DHA GC run time and post-processing data review can be lengthy.

GC with vacuum ultraviolet (VUV) spectroscopy (modified ASTM D8071) offers a faster way to estimate PMI.  Because of their unique absorbance spectra, the low-volatility mono- and di-aromatics responsible for most of the PMI are easily quantified with VUV, even in the presence of interfering isoparaffins, olefins, and naphthenes.

Digital Copper corrosion measurement vs. Visual rating _ Incorporating new technologies to method development

Aaron Mendez - Ayalytical Instruments
Juan Ayala - Ayalytical Instruments

pdf icon Download the presentation

Crude oils and Petroleum products contain sulfur in many different compound types that are associated with the increase of corrosiveness with the well know negative impact on operation efficiency. Ayalytical Instrument has developed a series of instruments based on digital detection imaging and a classifying visual algorithm displays automatically very accurate, corrosion ratings in seconds with an extraordinary repeatability. Test Method D130 is an important test method that measures corrosion on a standardized copper strip and is cited in numerous product quality specifications. The revision of D130 to incorporate an automatic rating procedure is part of the natural technological method development that has been observed in ASTM ever since its foundation. The revision brings numerous advantages to the current biased corrosion assessments in terms of unambiguity, speed of analysis and precision, which are undoubtedly beneficial. There a series of concerns however that need to be clarified before a ballot action of this sort passes the D2 Committee balloting process. Among these concerns perhaps the documentation of the new procedure and its correlation to the current visual procedure is one of the most important one. Experimental Results to be presented will address the issues of correlating the automatic procedures to the conventional visual rating.

Automating Spectroscopy Calibrations

Brian Rohrback - Infometrix, Inc.

A consortium of companies has undertaken a project to reduce the effort devoted to producing, maintaining, and stabilizing optical spectroscopy performance in routine quality assessment. Over a five-year period, the group has examined an unprecedented historical collection of spectra from multiple spectrometers spanning 1-5 years from sixteen oil refineries, with the goal of developing and maintaining stable models for long-term deployment. Even though the data are tied to petroluem work, the lessons learned are true for all applications. The technologies utilized follow a pattern of best practices, including the use of Robust outlier diagnostics, local and hierarchical modeling, and model augmentation. The effort has resulted in significant progress towards automation of model creation, stability, and maintenance in an industrial process. Additionally, we will share a comparison of prediction capabilities of different spectroscopy technologies and form-factors that can lead to a significant reduction in deployment and maintenance cost.

DSC and TGA 101: Introduction to Thermal Analytical Techniques

John Erne - NETZSCH Instruments

Differential Scanning Calorimetry (DSC) is the foundational technique for understanding phase transitions in materials, compounds and mixtures.  Along with GC, MS and FTIR it is the among the most commonly used analytical technique in the oil and gas, chemicals and polymers industries.

Thermogravimetric Analysis (TG or TGA) provides compositional information composition of solid and liquid materials, and is the primary method for determining thermal stability.  It can also be easily coupled to GC-MS and FTIR as a more advanced alternative to Headspace or Pyrolysis systems.

This training session will focus on the application of these techniques to both the QC and R&D environments -- where do they fit into the analytical toolbox in your day-to-day operations?

High field FT-ICR mass spectrometry has changed the utility and expectations of complex mixture analysis by mass spectrometry over the past decade. The inherent high resolving power and high mass accuracy enable direct determination of elemental compositions to tens of thousands of individual components by mass measurement alone. However, to obtain structural information, separations are often required. Here we highlight GC x GC, prep LC, and online LC/MS techniques in petroleum / environmental science, and discuss recent advances that enable an increased compositional and structural characterization of complex petroleum samples for upstream, downstream, and environmental applications.

Analytical methods for determination and quantification of olefins/diolefins in cracked petroleum streams

Rafal Gieleciak - Natural Resources Canada
Kirk Michaelian - Natural Resources Canada
Nicole Heshka - Natural Resources Canada
Cecile Lay - Natural Resources Canada
Jinwen Chen - Natural Resources Canada

Olefins and diolefins, highly reactive hydrocarbon compounds often found in cracked petroleum products, may be responsible for the formation of gums and solid deposits in storage tanks as well as in refining equipment (fouling). Several specifications are in place to regulate the levels of olefins in both unprocessed and finished petroleum products. This creates an imperative need for the ability to rapidly monitor and quantify olefin content in petroleum products. The current specifications for total olefin and diolefin content are set by a standardized 1H-NMR method and the UOP -326 diene value, respectively. These methods have several shortcomings including long analysis times and the need for expensive equipment. Furthermore, neither test provides any details on the type or distribution of olefins present in cracked petroleum streams. This presentation will review and compare existing methods used for olefin determination, as well as describing new methods that are currently under development at CanmetENERGY in Devon. These new methods include infrared and Raman spectroscopy, one and two-dimensional gas chromatography with vacuum ultraviolet and nitrogen chemiluminescence detectors, high-performance liquid chromatography, solid phase extraction, and derivatization methods. The principles and procedures of each method, as well as their advantages, limitations and applications to specific petroleum products, will be discussed.

In order to perform detailed studies on the source, transport, and ultimate fate of acute and chronic releases of petroleum hydrocarbons, high-resolution separations of target and non-target compounds and compound classes from complex mixtures such as petroleum frequently require techniques with high resolving power.  Comprehensive two-dimensional gas chromatography (GC×GC) coupled with flame ionization detection (FID), time of flight mass spectrometry (TOF-MS), and high resolution time of flight mass spectrometry (HRT-MS) are three of the high resolution tools employed in our laboratory for high fidelity chromatographic separations of useful biomarker compounds (molecular fossils) for petroleum forensics.   Here we present a number of examples of crude oil fingerprinting examples utilizing traditional and un-traditional oil spill forensic compounds in order to gain a more complete understanding of (a) which compounds persist in the environment and (b) how we can use high resolution techniques to forensically identify specific petroleum sources.

Fast Analysis of Non-Traditional Gasoline Additives with Gas Chromatography – Vacuum Ultraviolet Spectroscopy

Ryan Schonert - VUV Analytics
Dan Wispinski - VUV Analytics
Jack Cochran - VUV Analytics

Non-traditional gasoline additives (NTGAs) like ethyl acetate are being researched as beneficial octane-booster replacements for ethanol and methyl tert-butyl ether.  Other octane-enhancing NTGAs, including acetone and N-methylaniline which can degrade automobile engine performance, are sometimes used illegally in gasolines outside the United States and Europe.  Unfortunately, monitoring programs relying on ASTM D6730 (Detailed Hydrocarbon Analysis) and ASTM 6839 (Multidimensional Gas Chromatography) do not include most NTGAs in their scope.  

Gas chromatography (GC) with vacuum ultraviolet spectroscopy (VUV) offers an easy way to accurately quantify NTGAs in gasoline with authoritative absorbance spectra confirmation of their presence.  GC-VUV run time is less than 34 min and data processing is fully automated.

Hydrocarbon type analysis has become an important technique in the screening and evaluation of jet fuel quality and alternative fuel suitability. GCxGC is routinely used to characterize fuels for hydrocarbon type; it incorporates both quantitative FID and qualitative MS identification with flow modulation. The simultaneous FID-MS is convenient since compound class groups are more easily characterized on the MS channel and then immediately applied to the FID for quantification. Recently, thermal modulation with dual FID-TOFMS has been developed for column systems similar to the flow modulation system; results are being compared for the two different modulators for hydrocarbon type of petroleum and alternative fuels.

Using Static Headspace GC-VUV to Detect Methanol in Crude Oil

James Diekmann - VUV Analytics
Ryan Schonert - VUV Analytics
Dan Wispinski - VUV Analytics
Jack Cochran - VUV Analytics

Methanol is used in the production of crude oil to prevent formation of gas hydrates. Residual methanol in crude oil can lead to costly problems in refinery operations, especially with wastewater treatment.  Typically, direct-injection multidimensional gas chromatography is used to determine methanol in crude oil via ASTM D7059.   

Static headspace gas chromatography – vacuum ultraviolet absorbance spectroscopy (SH GC-VUV) offers an attractive alternative to the complex hardware setup for ASTM D7059.  A working concentration range of 5 to 1000 ppm can be achieved, with VUV spectral confirmation of methanol in crude oil.  Headspace analysis eliminates the GC inlet and column lifetime problems associated with ASTM D7059.

Mud logging provides important data to the exploratory drilling industry, traditionally this data is provided by an isothermal GC method, and while the results were reliable and helped to correlate understanding of depth and content, the method was slow.  An improved method using a rapid heating technology to temperature program the analytical column can achieve significantly quicker analysis, and much improved separation of sample constituents.  This technology greatly reduces the heating/cooling cycle time, while also providing much higher resolution.          

This Valco developed technique uses cold on-column injection, with an extremely accurate and fast heating technology with a unique temperature measurement/application method.  This technology greatly reduces not only the heating and cooling times, but also the size and power required for instruments doing this analysis.          

This temperature control technology is not limited to columns, but can be applied to injectors, transfer lines, and other components as required.  The application of this technology can provide higher throughput and higher resolution well beyond the capability of traditional GC techniques. The total cycle time for this enhanced C1 to C5 analysis with seven components is less than 20 seconds with a total recycle time less than 45 seconds.  In this presentation we will describe the details of this technology, its configuration, and our test results.

Preconcentration is more and more used in environmental analysis, and more widely in trace level analysis. Unknown samples have been treated that way for many years. However, the calibration of the analyzer itself has been an issue. Calibration with concentrated gases injected directly into the analyzer and unknown samples analysis through a preconcentration process may yield to a significant bais. 

This presentation will describe an automated, multipoint, low level calibration gas preparation device, including heavy compounds which are not vialble in gas cylinders. 

Different applications such as the determination of hydrocarbon contaminants in hydrgen fuel, ambient air analysis, trace of sulfur in gases, etc. will be described.

The measurement of CO, CO2, and formaldehyde is important across many industries, including renewable fuels, transformer oil gas analysis, and food & beverage. Historical techniques for this analysis have included the use of a TCD or a Ni-catalyst methanizer paired with an FID, however these techniques suffer from poor linear range and robustness, respectively. In recent years, advances in catalysis have allowed for a new analytical technique to emerge, the Jetanizer. The Jetanizer, which uses novel catalysts and a stainless-steel 3D printed design, allows for in-situ methanation with the FID for a simplified approach and a linear dynamic range of over six orders of magnitude.

The heartbeat of the process environment is in the data we collect, but we are not always efficient in translating our data streams into actionable information. The richest source of hydrocarbon process information comes from spectrometers and chromatographs and, for many applications, gas chromatography is the cheapest, most adaptable, and most reliable technology available.  We can use tech borrowed from other fields to provide more consistent and objective GC results, automate translation of the raw traces into real-time information streams, and create databases that can be used across plant sites or even across industries.

Real-Time Monitoring of Key Jet and Diesel Parameters Via Raman Spectroscopy

Lee Smith - Process Instruments, Inc.

Improving distillate throughput in a refinery is an ongoing battle since the difference between the specifications and the measured properties directly effects profitability. Blending distillate fuels is tricky because there are typically many blend components coming from different units within the refinery, i.e. Crude Distillation Unit, Hydrocracker, Vacuum Distillation tower, and Hydrotreater to name a few. It is important to carefully monitor these rundown streams in real-time to optimize fuel properties while maximizing profitability. Raman spectroscopy and its narrow, well defined spectral peaks has demonstrated an ability to easily monitor key distillate fuel blend and finished stream properties in real-time. For Jet, this includes properties such as: Freeze, Flash, Smoke points, and distillation points.   Raman’s enhanced sensitivity to aromatics makes measuring Smoke point very simple.  All of these tests can be run in < 2 minutes. With Diesel, Raman can easily monitor Cetane, Cloud, Flash and Pour Points in addition to Aromatics, distillation points and total sulfur. Our use of best-practices PLS chemometric modeling and hierarchical models allows refiners to optimize model performance throughout their distillate blends. This type of close monitoring affords refineries opportunities for blending extra naphtha and even heavy stocks directly into diesel and Jet for increased profitability.

Analyzing Live Crude: Complete C1 to C100. How much information can we get?

Chris Goss - Innotech Alberta
Amanda Prefontaine - Innotech Alberta
Lee Marotta - PerkinElmer

A “live” crude is when the sample is preserved so that the more volatile components are not lost in collection and in sample transfer.  This is critically important for light crudes where the sample has a significant amount of lower boiling components, thus providing more accurate boiling point distribution.  

ASTM D7169 (high temperature simulated distillation), does not analyze a live crude oil. ASTM D8003 injects a live crude oil but it only provides information from nC1 to nC24 due to inlet discrimination.  

Using a High Pressure Liquid Injection System (HPLIS) in conjunction with micro fluidic valves a complete analysis from nC1 to nC100 can be achieved.

Limit of detection for Sulfur in Aromatic matrices

Robbert Van Wessel - PAC LP

 This seminar focuses on how to calculate limits of detection when analyzing trace amounts of total sulfur concentrations in aromatic matrices with a total sulfur UV-fluorescence combustion analyzer.  The limit of detection of an instrument is specified by the ability to differentiate an unknown sample from a blank or basic state with a certain probability. To determine the minimum detectable value of an unknown, the precision of the limit of detection increases by not only using the linearity of the calibration but also the residual standard deviation over the whole range of the calibration. furthermore, by increasing the number of replicates and levels, the certainty is increased which will result a more confident number of limits of detection.

Online GC analysis has advantages of providing immediate feedback on processes, avoiding the need to grab samples that are gaseous or hazardous. Compared with the traditional platform where a fixed sample loop and isothermal oven design are used, the Agilent online GC has advantages of split injection and temperature ramping capability. We report here that a combination of split injection and a back-flushing valve configuration had issues of nonlinear response vs split ratio or the GC not reaching the “ready” status under a high split ratio set. The reasons contributing to these observations and measures to mitigate these issues will be presented.

Process Raman Gas Analysis in Refining-Update

Susan Harris - Endress+Hauser

On-line process measurement of the composition of gas streams in refining, fertilizer, and other manufacturing industries is essential for the optimal operation of different process units within these facilities. Process analyzers based on gas chromatography, mass spectrometry, and electrochemical technologies are commonly used in these facilities. However, process conditions for certain streams present major challenges for these traditional technologies. Techniques based on optical spectroscopy, including near-infrared (NIR), infrared (dispersive and Fourier transform), and Raman spectroscopy, can provide analysis solutions for these challenging stream conditions. Raman spectroscopy is particularly useful for streams containing homonuclear diatomic gases, such as H2 and N2. Hydrogen is an essential feedstock for the hydrotreating, hydrocracking, and catalytic reforming of various hydrocarbon fractions in refineries. A case study will be presented for optimization with the analysis of hydrogen, hydrogen sulfide and other compounds in the hydrogen recycle process in a refinery hydrotreater/hydrocracker and for hydrogen purity measurements in a hydrogen plant.

Combatting Corrosion in Refineries: Using Ion Exclusion Chromatography to measure Free Cyanide in Sour Water

Jay Sheffer - Metrohm USA

Corrosion is always a chief concern for petrochemical refineries.  One of the key steps for processing sour crude oil or gases is desulfurization.  Amine treaters are commonly used for this purpose.  In amine treaters, acidic gases such as SO2, SO3, CO2, NO, and NO2 form Heat Stable Salts (HSS).  However, since high amounts of carbon and nitrogen are available, cyanide salts may also be formed in the process.  Not only is cyanide toxic, but it is particularly corrosive to refinery equipment.  Therefore, refineries wish to monitor cyanide concentration as hydrogen cyanide (HCN) in their processes on a regular basis.  This paper presents a method by which free and available cyanide concentration is measured using ion-exchange chromatography down to 5 parts-per-million without pretreatment and without interference in a sample matrix containing up to 3% H2S.

Simple, Efficient Petrochemical Analysis with NIR and Raman Spectroscopy

Adam Hopkins - Metrohm USA
Raghvendra Sengar - Metrohm USA

Traditional ASTM protocols for testing petrochemical products are often time-consuming processes, require highly skilled labor, or have high consumables costs. These drawbacks reduce the efficiency and profitability of plant operations, despite the existence of well-proven alternative technologies such as near infrared (NIR) and Raman spectroscopy that are well-described in ASTM E-1655. This talk explores the basics of implementing efficient spectroscopic methods in the context of the ASTM standard practice, citing the benefits for specific examples such as lubricant oil testing, ethanol blending, diene value, and amine strength.

Moisture Analysis of Solids, Liquids and Gases

Kerri-Ann Blake - Metrohm USA
Lori Spafford - Metrohm USA

Moisture can also increase corrosion and lead to catastrophic failure. There are several techniques for determining moisture or water content. Karl Fischer (KF) analysis is the only technique chemically specific for water and can be performed on solids, liquids, and gases. Complimentary to KF, near infrared spectroscopy (NIR) reduces analysis time and eliminates the need for additional chemicals. This technique can be applied at the benchtop or as an online analyzer. This talk will discuss the analysis of different sample types by Karl Fischer titration and how this data can be funneled into NIR for faster, reagent free analysis.

Using Mass Spectrometry as an Ion Chromatography Confirmation Tool For The Determination of Alkylamines and Alkanolamines in Scrubbing Solutions

Carl Fisher - Thermo Fisher Scientific
Terri Christison - Thermo Fisher Scientific
Jeff Rohrer - Thermo Fisher Scientific

pdf icon Download the presentation

Amine scrubbing or neutralizing solutions are used routinely to prevent corrosion during transportation to the refinery or to remove sour gases during the refining. Alkylamines are contaminants originating from the alkanolamines functioning in their neutralizing role. In the complex samples characterized by processing plants during refining, molecular confirmation is often needed for compounds identified chromatographically. Ion chromatography coupled to an electrospray ionization mass spectrometer (IC-ESI-MS) is an ideal and economical way to determine and confirm amines. Here we demonstrate amine contaminant determinations in amine solutions by cation-exchange separation followed by suppressed conductivity and ESI-MS detections in a serial configuration.

Polyarc Advancements Reduce the Dependence on Complex Standards for Trace Impurities by GC/FID

W. Christopher Siegler - The Dow Chemical Company
Marla Gilbert - The Dow Chemical Company
James Griffith - The Dow Chemical Company
Bill Winniford - The Dow Chemical Company
Jim Luong - The Dow Chemical Company
Andrew Jones - Activated Research Company

In the chemical industry, the determination of trace impurities in a manufacturing process necessitates the quantification of complex mixtures in various matrices. These analyses present a significant challenge due to the complexity of the analytes (chemical functionalities ranging from oxygenates to chlorinated compounds) and the need for multi-level calibration to account for the varied response of these analytes by GC/FID. Here, we demonstrate the rapid and accurate quantification of a wide variety of compounds for trace impurity analyses using a commercial post-column reaction system from ARC called the Polyarc Ultra. Accurate quantification without complex calibration standards simplifies the workflow in analytical determinations and reduces the potential for errors associated with calibrations and sample handling.

Characterizing Stationary Phases for GC x GC with Representative Probes

Bill Winniford - The Dow Chemical Company
Raymond Jaramillo - Penn State University
Matthew Klee - XO Associates
Frank Dorman - Penn State University

In this study retention indices were measured for a set of 11 probe compounds of differing chemical functionality on a range of open tubular capillary columns: Rxi-1ms, Rxi-5ms, Rxi-35 Sil-ms, Rxi-17 Sil ms, Rtx-200, Rtx-2330, Rtx-Stabilwax. GC x GC applications have most often done with a non-polar (PDMS) phase followed by a polar phase (typically polyethylene glycol wax).  The second most common configuration is the reverse of this, polar followed by non-polar.  The potential combinations of capillary columns with unique selectivity is well over 100.  This is too many for an iterative approach and comparative retention index data is limited primarily to PDMS phases and wax phases.  The results of this study give examples of how much functional groups affect retention changes with column phases.  Kovats retention indices are based on the nearest Cn and Cn+1 n-paraffins to the component of interest and are intended to compensate for column, instrument and laboratory variability.  But as stationary phase polarity increases hydrocarbon retention decreases significantly.  In GC x GC it is important for components to elute in a relatively narrow capacity factor window on the second dimension column so it is important to also measure absolute retention.  The data from this study are useful in estimating the relative retention with new GC x GC column combinations.

Sediment material from corrosion (containing magnetic iron, oxide based) has been found accumulating in pumps, valves, on pigs and in line inspection tools.  

Some of the key players in corrosion are oxygen (O2), carbon dioxide (CO2) and hydrogen sulfide (H2S). These can cause corrosion when present in the low ppm to ppb range. A robust, reliable method to detect trace levels of dissolved corrosion gases (O2, H2S and CO2) in pipeline products does not exist. A method was developed that uses a liquid phase injection, a backflush so the fixed gas column does not get contaminated, and a sensitive detector. Low ppm detection limits were achieved.

Solid-state cooling/supercooling of viscometer baths

Mohammed Ghorabian - PSL-rheotek & Anglia Ruskin University
Javaid Butt - Anglia Ruskin University
Stephen Gosling - PSL-Rheotek
Hassan Shirvani - Anglia Ruskin University
Akhtar Mahmood - PSL-Rheotek

Thermoelectric heat pumps (Peltier cooler/ heaters) are simple differential thermocouples and use the thermoelectric effect for transference of heat with the application of an electric current. The physics and engineering effects of such devices have been studied extensively under the steady current supply and are now being used commercially for moderate sub-zero applications. In these cases, the cooling coefficient of performance and maximum temperature drop depends on the material constants of the thermoelectric materials used through the figure of merit, theta = a^2/(Rk)^2  , where a = Seebeck coefficient, R = electrical resistivity, and  = the thermal conductivity. Briefly, this is because the heat removed due to Peltier cooling, Q = R T I, which is proportional to the applied current I, is counteracted by Joule heating proportional to I 2R and the reverse conductive heat flow proportional to k. Since Joules heating is proportional to a higher power of I than the thermoelectric cooling term, there will be a current, Imax, which produces the largest difference in temperature DTmax,  Since cooling of the differential thermocouple occurs at the junction at the cold end of the thermoelectric elements. Joule heating, however, occurs uniformly throughout the thermoelectric elements. Thus, when current is applied, the cooling at the cold junction occurs before the Joule heat reaches the cold end. In this study for the application of viscosity measurements in uniformly cooled baths a cascade of devices together with a specially designed water block was used to reach low and sub-zero temperatures whilst transient method was proposed to achieve supercooling. Such devices will be demonstrated and further discussions will be held to discuss the performance and the technology in a workshop session.

On-line supercritical fluid extraction-supercritical fluid chromatography–mass spectrometry (SFE-SFC-MS) provides a platform for analyte extraction, separation, and detection, while limiting sample preparation, sample loss or contamination, and significantly decreasing total analysis time. Limited examples for SFE-SFC-MS in quantitative analysis have been reported. This is likely due to the inherent complexity of the system.  Here, we systematically evaluated user-definable variables in the system by response surface methodology to establish a basis for method development in determining analytes of varying polarity and classes across sample matrices of varying retentivity to elevate this platform to a more user-friendly and accessible technology.

Determination of the Wax Appearance Temperature (WAT) by DSC

Samantha Nania - PerkinElmer

Crude oil is primarily composed of hydrocarbons, some of which are naturally occurring paraffins (CnH(2n+2)). Paraffins that contain ≥16 carbons and form crystalline solids at ~20°C are known as waxes. Because these high molecular weight waxes can crystallize at low temperatures, they can cause problems at every step in oil production and refining due to solid deposition. The temperature at which this crystallization occurs is called the wax appearance temperature (WAT). Previously, WAT characterized visually as described in ASTM D2500. Here, we show a more precise and scientific way of determining the WAT using differential scanning calorimetry (DSC).

Olefin Content in Fuels by ASTM D8071

Jean-Francois Borny - McDermott Technology

Removal of ppm sulfur in fuels is regulated by Tier 3 Gasoline mandate from the EPA. Through a process known as hydrodesulfurization, large-scale oil refineries attempt to remove the majority of sulfur from fuels without modifying the composition of the major components, such as olefins and aromatics.  Hydrodesulfurization employs catalytic conversion to remove the sulfur while maintaining the other components of interest. It is therefore necessary to have analytical methodology that accurately represents those components.  ASTM D1159, bromine number by titration, has been the standard for design engineers to determine the olefin content of the fuel.  Detailed Hydrocarbon Analyses (DHA), such as ASTM D6733 and D5134, have improved over time but are problematic when determining the olefin content in order to calculate heat balance and hydrogen consumption for unit design. A 2007 article in Energy & Fuels by Podrebarac and Judzis compared these methodologies and concluded that ASTM D1159 approximated the olefin content better than the other methodologies for large-scale refinery unit design.   This presentation will address the reason D1159 works better for design, review original and new data based on D1159, D6733, D5134 and D6839 and explore a newly approved ASTM method, D8071, a Vacuum UltraViolet (VUV) detector. Is ASTM D8071 a solution for olefin content determination?

MALDI-TOF-MS fingerprinting of Friction Reducers

Dino Camdzic - University of Texas at Arlington

As hydraulic fracturing becomes more common, methods to analyze these complex additives are essential. Friction reducers are a type of enhanced oil recovery additive used in the hydraulic fracturing process to reduce friction and backpressure in the pipes while pumping at high flow rates. Matrix-assisted laser desorption/ionization – time-of-flight (MALDI-TOF) mass spectrometry was used to identify the polymer content in six different commercial friction reducers. Each friction reducer was tested at lab-simulated downhole conditions in various matrices including deionized water, produced water inorganic, and produced water with and without the addition of shale core. The goal was to qualitatively determine the polymer content in the friction reducers and their proclivity to degrade to various components at lab-simulated subsurface conditions. The methods developed here using the MALDI-TOF-MS could be implemented as a quick and straightforward approach to detect polymer content in produced water and wastewater for fingerprinting. The methodology is also useful for understanding the stability of these additives under down-hole conditions.  Two different polymers containing carbon chains of 12 and 14 with varying degrees of ethoxylation ranging from 6-18 were detected, which was consistent with the MSDS data sheets.

Characterization of Benzene, Toluene, Ethylbenzene, and Xylenes within Friction Reducers using Headspace-Gas Chromatography-Mass Spectrometry-Vacuum Ultraviolet Spectroscopy

Robert Magnuson II - University of Texas at Arlington

A method of fossil fuel extraction that has become more common is known as hydraulic fracturing. This unconventional process allows for the harvesting of oil and gas resources from low porosity shale. This procedure is characterized by pumping a liquid mixture, often with sand suspended in it, underground and fracturing the subterranean rock formations, to release the sequestered fossil fuels. A common component of the hydraulic fracturing method includes the use of friction reducing additives (FR) to aid in the pressurizing of the well and to minimize flow resistance during the extraction process. FR are complex and variable mixtures, which contain petroleum products.  These may include benzene, toluene, ethylbenzene, and xylenes (BTEX), all of which present potential toxicity hazards to the ecosystem if they are present in HF or waste fluids, which are mishandled and spilled. A analysis of 6 FR was conducted using headspace-gas chromatography combined with split detection, to a triple quadrupole mass spectrometer and a vacuum ultraviolet spectroscopic detector (VUV). VUV was selected because it is complementary to the MS/MS in that it allows for the deconvolution of co-eluting xylene isomers and characterization of the various compound classes contained therein.

Differentiation of Phthalate Esters through Gas Chromatography- Vacuum Ultraviolet Spectroscopy with Isomeric Resolution

Michelle Reyes - University of Texas at Arlington

Phthalate esters are used heavily to soften and increase the flexibility of plastics in consumer and personal care products. They have been produced commercially in great quantities since World War II, and can be easily found in food, water, and air due to excess use and bleaching of plastics. Phthalate esters are known to be toxic, teratogenic, mutagenic and carcinogenic towards humans and animals. The length of the alkyl side-chains (from C1 to C13) as well as their isomeric structures (e.g. butyl phthalates) can lead to significant differences in toxicity. Distinguishing which phthalate esters are present in environmental samples is important for quantifying their potential toxicity. In this study, we investigate how gas chromatography-vacuum ultraviolet spectroscopy (GC-VUV) can distinguish phthalate esters that are common in environment and have similar structures. GC-VUV is able to distinguish between compounds which have shown co-elution in GC or isomeric species. Here, we report GC-VUV experiments on a wide range of phthalate standards with different alkyl chain substitution, including isomeric n-butyl, n-hexyl, and n-octyl phthalates. The results quantify the potential of GC-VUV for differentiating toxic phthalate esters in the environment.

Improved ICP Performance with Precise Temperature Control for Petrochemical Applications

Justin Masone - Glass Expansion Inc

The analysis of organic solvents by ICP-OES and ICP-MS is often seen as challenging and problematic due to their volatility, as well as their high carbon content. As a result of their increased volatility, organic solvents have a higher transport efficiency, which can destabilize, or even extinguish, the plasma. The high carbon content can lead to carbon build-up (soot) on the interface cones of an ICP-MS, blocking the orifice and leading to signal drift; in addition, the carbon content can lead to a drastic increase in carbon-based spectral interferences (e.g. 40Ar12C+ on 52Cr+). This is especially true for highly volatile solvents such as naphtha, a mixture of petroleum distillates of wide industrial importance. Historically, naphtha would be diluted with a less-volatile solvent, such as kerosene, which not only presents an unnecessary opportunity for error and contamination to be introduced, but also prevents lower levels of detection from being reached. Utilization of the IsoMist XR, a temperature-controlled spray chamber, eliminates the need for dilution, and it allows for direct analysis of naphtha (as well as other organics) at a temperature of -25 °C, resulting in the highest intensities, best precision, and best accuracy available.

Analysis of the ARC Jetanizer for CO2 and CO In-jet Methanization on Shimadzu Gas Chromatographs

Allison Mason - Shimadzu Scientific Instruments, Inc.

Carbon monoxide and carbon dioxide are common targets for a broad range of applications from greenhouse gas monitoring to refinery gas emissions. Low sensitivity of CO2 and CO through using Thermal Conductivity Detection (TCD) methods and the lack of detection from Flame Ionization Detection (FID) makes detection sensitivity a challenge. Methanization is a method using a nickel catalyst to convert CO and CO2 into methane which can be detected using FID, a detector known to exhibit high levels of sensitivity and a broad range of linearity. Traditionally, methanization must be performed using a separate unit added prior to the FID for operation which can be costly , provides limited linearity, and is susceptible to degradation from sulfur containing compounds and oxygen.. Activated Research Company (ARC) has developed an in-jet methanizer (jetanizer) which can be installed with no modification or permanent alteration to the instrument setup. The jetanizer   provides low level detection of CO and CO2 with a wide linear range with less susceptibility to catalysis poisoning by high oxygen samples. The goal of this analysis is to analyze the efficacy, durability, and reproducibility of ARC’s Jetanizer on Shimadzu Gas Chromatographs.

Challenges of Non-aqueous Automated Titrations in the Chemical Industry

Ana Nunez - Dow Chemical

Titration techniques are widely used in the Chemical Industry for product and raw material characterization and qualification. Many of these titrations require a non-aqueous environment, leading to difficulties due to reduced response in a low conductivity media. Advancements in the field of automated titrators and sensor design have created opportunities for analysis at very low levels, in difficult matrices. Several methodologies and current challenges of non-aqueous titrations will be discussed, including matrix and solvent effects, electrode response, electrode conditioning and maintenance, low level detection, as well as the motivation to overcome these challenges to improve on elucidation of product quality.

Applying Risk-Based Thinking to Laboratory Operations

Gretchen McAuliffe - Labtopia

There is a shift in the focus of ISO-based standards to a proactive, preventive approach to quality management rather than reactive, incident-based response.  This extends to laboratory operations as well, particularly with the latest revision of ISO 9001:2015 and the ISO 17025:2015 standards.  One of the fundamental continual improvement tools used to implement such a cultural change is risk management.  When companies perform risk analysis, they can effectively identify areas of weakness within operations and the likelihood that the harm would occur prior to an actual event.  Once analyzed, labs can implement control measures to mitigate the impact of harm.    Additionally, risk analysis allows managers to focus valuable resources on improvements for the most vulnerable processes and methods.  This seminar will discuss how management professionals can apply risk-based thinking to all laboratory operations to improve quality and reduce laboratory errors.  In addition, application of a common risk analysis tool will be presented. .

Simple, Efficient Petrochemical Analysis with NIR and Raman Spectroscopy

Adam Hopkins - Metrohm USA
Raghvendra Sengar - Metrohm USA

Traditional ASTM protocols for testing petrochemical products are often time-consuming processes, require highly skilled labor, or have high consumables costs. These drawbacks reduce the efficiency and profitability of plant operations, despite the existence of well-proven alternative technologies such as near infrared (NIR) and Raman spectroscopy that are well-described in ASTM E-1655. This talk explores the basics of implementing efficient spectroscopic methods in the context of the ASTM standard practice, citing the benefits for specific examples such as lubricant oil testing, ethanol blending, diene value, and amine strength.

Improved ICP Performance of High-Solids Samples: Increase Precision and Decrease Downtime

Justin Masone - Glass Expansioin, Inc

A sample matrix high in total dissolved solids (TDS) can be a considerable challenge in ICP emission spectroscopy. Since many “real world” samples commonly contain high TDS, it can often be a struggle to optimize ICP analyses for both sensitivity and robustness. Typical problems encountered when analyzing high TDS samples include: interrupted runs and increased downtime, signal drift and suppression, clogged nebulizers, significantly-shortened torch life (devitrification), and physical interference and transport effects. General solutions often include matrix-matching, which can be a difficult problem in itself, dilution, and using dedicated radial-view systems (both of which lead to loss of sensitivity). Alternatively, these problems can be overcome with relative ease by selecting the proper sample introduction configuration; long-term stability when analyzing brines, acid digests, soils, sludges, wastewater, and fusions can be achieved by with the right selection of high-TDS glassware and accessories, resulting in increased sensitivity and precision, as well as decreased maintenance and downtime.

Comprehensive Environmental Testing of Groundwater Quality in the Alpine High Region

Hailee Anderson - The University of Texas at Arlington

Concerns persist around the potential environmental impact of unconventional oil and gas extraction processes.  Yet, some industry operators have taken steps to enable third-party monitoring of water quality in and around their operations.  In this study, a myriad of custom analytical approaches were used to study the groundwater quality in the Alpine High region of West Texas, an area of increasing oil and gas development. Several batches of samples were collected over time from the Balmorhea State Park and surrounding areas to create a baseline for monitoring the potential occurrence of contamination, from chemicals, such as hydrocarbons and other organics, to abnormal minerals and bacteria. The groundwater samples were analyzed by gas chromatography - mass spectrometry (GC-MS) and headspace – gas chromatography - flame ionization detection (HS-GC-FID), as well as by total organic carbon (TOC) and total nitrogen (TN) analysis. Metals, anions, and the presence of bacterial communities were also assessed by other appropriate analytical methods.  TOC and TN provided bulk water quality information; this data can help understand whether abnormalities might be attributed to industrial or agricultural processes. GC-MS is a sensitive technique that was used to identify volatile and semi-volatile compounds present in the sample, while HS-GC-FID was better for assessing highly volatile constituents, such as alcohols. The data collected from the groundwater samples was compared to that of analytical grade (Millipore) water. As of now, monitoring continues, but no significant abnormalities have been detected in samples collected in the Alpine High region.

ASTM D7798 Fast SimDis Analysis using Shimadzu Nexis GC-2030 and the Valco Fast Temperature Program module

Ryo Takechi - Shimadzu Scientific Instruments, Inc.

A new ASTM SimDis method - ASTM D7798 has been released.  This method is similar to ASTM D2887 except it applies to ultra-fast gas chromatograph technology, which drastically shortens the analysis time. While the Shimadzu Nexis GC-2030 has an industrial-standard GC platform which works for ASTM D2887, with the integration of a Valco Fast Temperature Programmer (FTP), applied to injector, column, and transfer lines, ASTM D7798 can now be run on the Nexis GC-2030. Thus, now the customer can run both the ultra-fast and conventional/typical GC analysis on one GC. In this presentation, we will present the performance data to show the capability of this GC platform running ultra-fast chromatography.

Techniques to speed up the analysis in gas chromatography

Katarina Oden - Restek
Christopher Rattray - Restek
Jaap de Zeeuw - Restek
Keith Irwin - Restek

In this seminar, we will discuss options to reduce the analysis time in gas chromatography without major investment in equipment nor investment in time to redevelop existing methods.
Ways to speed up the analysis depends on the resolution between the components of interest. Whenever there is plenty of resolution between the compounds the analysis time can be decreased by simply shortening the column or increasing the flow rate. However, in cases where we do not have extra column efficiency, the options are to switch to a more efficient carrier gas or use shorter, narrow bore, thinner film columns. Regardless of the choice, to maintain the elution order between the compounds or preserve resolutions, the methods have to be properly translated.
Practical examples will demonstrate:
  1. Using Restek’s EZGC method translator to speeding up the analysis while scaling down to smaller, high-efficiency, narrow-bore columns.
  2. Presented will be a migration of ASTM D2887 simulated distillation from a slower procedure A to faster procedure B using a slow, 120V oven and the GC Accelerator kit. The GC Accelerator kit provides a simple way to speed up sample analysis. By reducing oven volume, these inserts allow faster ramp rates to be attained.
  3. Speeding up a DHA run by increasing the flow on a long, narrow bore column.

This presentation will detail work being highlighted in the poster “Fast Separation of Heat Stable Salts.” Hydrogen sulfide (H2S) and carbon dioxide (CO2) are often found in natural gas streams and are removed using amine-rich solutions before it can be transported/used. During this process, heat stable salts (HSS) can form as a result of an irreversible reaction of the amine with certain acidic components. Because HSS are corrosive, it is important that they be monitored. Here we present an Ion Chromatography (IC) method that uses a high-capacity, hydroxide-selective anion-exchange column with a fast gradient to analyze various refinery samples for the presence of common inorganic anions and heat stable amine salts.

The quantitation of olefins in petroleum products is of great industrial interest, especially for those involved in transportation and upgrading of bitumen and heavier crudes by thermal cracking. Olefins and di-olefins produced in small quantities during the thermal upgrading processes have a tendency to undergo polymerization reactions causing instability to the finished products. The purpose of this research project was to identify and quantify olefins using Gas Chromatography (GC) and a Vacuum Ultraviolet (VUV) detector. The focus matrix was condensate but it has been used on upgraded bitumen. The research has resulted in method detection limits (MDLs) of more than 45 olefins and di-olefins including several conjugated olefins at very low part per million (ppm) levels with greater than 90 percent accuracy. Another 20 olefins have been detected in various samples. This presentation will discuss the research, analytical parameters such as precision, detection limits, method dynamic range and accuracy, and the results from sample data.
