Utilizing a Novel Microfluidic Viscometer for Fast and Accurate Analysis of Materials at Low Viscosity and High Shear

Matt Vanden Eynden - Formulaction, Inc.
Patrick Abgrall
Patrycia Adamska
Yoann Lefeuvre
Gerard Meunier

Understanding the behavior of materials under varying shear rates will help deliver quality results and projections of a materials performance. Using rheometers or rotational viscometers may not provide access to optimal viscosity and shear rate ranges with relative ease. Here, we utilize a novel device that employs a co-flow microfluidic principle to obtain the viscosity of various products as a product is run against a reference inside of a microfluidic chip. The confined, laminar flow allows access to high shear rates (> 10^5 s-1) while also performing at low viscosities (< 1 cP). Current examples and applications will be discussed.

Stability Analysis of Ashpaltene Dispersions and Crude Oil Demulsification Mixtures Using Multiple Light Scattering

Matt Vanden Eynden - Formulaction, Inc.

Detecting phase separation events in crude oil mixtures is of importance as to alleviate processing issues and optimize formulations. Shelf tests are adequate in some regards but are subjective and can often take long times in order to see results. The Turbiscan (Formulaction, France) uses Multiple Light Scattering (MLS) to quantitatively track particle migration and phase separation kinetics. This allows for asphaltene dispersions to be quickly tested for additive effectiveness and stability as per standard methods. The fast and resolved nature of the measurement can also provide demulsification kinetics relating to water and interface quality and speed of demulsification.

Low Level Measurements of Benzene Exposure in the Workplace and at ppt Levels at Fencelines via Gas Chromatography/Photoionization Detection

Jennifer Maclachlan - HNU PID Analyzers LLC
John N. Driscoll - PID Analyzers, LLC

Benzene is a known carcinogen and long term exposure to this chemical may result in leukemia. The Occupational Safety and Health Adminstration (OSHA) permissible exposure limit (PEL) for benzene, established in the 1980’s, was 1 ppm. In the 1980’s, tetra ethyl lead, an octane booster, was removed from gasoline and replaced with these aromatic hydrocarbons: Benzene, Toluene, Ethylene and Xylene (BTEX). In 1990, benzene was one of 189 hazardous air pollutants (HAPS) identified by the Environmental Protection Agency (EPA) in the Clean Air Act of 1990. As a result, the quantity of benzene in gasoline was gradually reduced to limit the benzene emitted to the atmosphere. In 2015, EPA announced a plan to regulate benzene at 2.8 ppb at the fenceline of refineries and chemical plants since neighbors of these facilities could experience exposure to low levels of benzene in the ambient air for 24 hours per day.

The OSHA limits (PEL = 1.0 ppm) for the workplace (chemical plants, gas pipelines, shipyards etc.) can be measured at the 1 ppm level using a portable gas chromatograph configured with a photoionization detector (GC/PID). The EPA limit of 2.8 ppb at refinery and chemical plants fence lines is near the detection limits for most GC/PID’s so a low power concentrator would be needed to measure sub ppb levels of benzene without interference from hexane or other alkanes present. A new mini hand-held GC based analyzer that will be able to measure benzene in the workplace at ppb levels and at ppt levels in refinery and chemical plant fencelines will be described.

Hydrogen Gas Lab Servers: An Advantageous Solution for Petrochem Chromatography

Scott Accetta - Proton Onsite
John Stevenson - Proton Onsite
John Speranza - Proton OnSite

Analyzing petroleum samples, performing hydrocarbon analyses and testing substances such as gasoline, biodiesel and natural gas can be time-critical and very costly if labs suffer delays in testing due to equipment downtime.  In many cases, laboratories procure instruments strictly based on their ability to generate fast, accurate results.  On-site hydrogen gas generation is the preferred source of carrier gas supply for chromatography equipment in the petrochemical industry due to its benefits of safety, reliability, and consistent composition.  Further, On-Site hydrogen generators are compact, streamlined systems that produce the carrier gas required on demand without the hassle and danger of high-pressure cylinder delivery.  Supporting petrochemical, refining, and chemical processing applications, Proton OnSite’s G4800 “Lab Server” hydrogen generator is ideally suited for testing environments that require multiple gas chromatographs.  The G4800 is the only generator large enough to handle all carrier gas requirements from a single source.  This unit employs Proton Exchange Membrane (PEM) cell stack technology to produce a reliable stream of ultra-high purity hydrogen (99.9999%) for point use.  This presentation aims to illustrate the advantageous results yielded by a Lab Server at a customer site performing petrochemical analyses.  In this instance, the customer sought alternatives to hydrogen delivery and explored procurement of on-site gas generation equipment.  Rather than opting for multiple gas generators, to support the hydrogen demand at their facility, this customer elected to implement a single centralized unit to conserve lab footprint, cost, and maintenance requirements.

The Importance of Chloride Measurement in Petroleum Samples

Michael C. Pohl - HORIBA Instruments, Inc.

Chloride is a ubiquitous element in earth's environment and plays a very large role in the Petroleum Industry.  In many environments it plays a very beneficial role, but in this industry it often has very detrimental effects.  From corrosion of metal components at a refinery to catalyst poisoning at a chemical plant, it has the potential to cost chemical processors huge sums of money. The problems are magnified because many processes are continuous and so even low concentrations can have a cumulative effect over time.

Chloride levels are typically low, which is a bit of a mixed blessing. They do not do their damage at a very rapid rate, but at typical PPM levels, are difficult to remove and challenging to quantitate. As with many Petroleum related challenges, over the years, a number of ASTM Methods have been written to address the acceptable levels of chloride and also how they can be determined. The specifications, as well as the appropriate analytical methods, will be reviewed and discussed. They will also be applied to very specific petroleum samples.

One of the most popular methods in use today is the combustion - microcoulometric analysis. This very simple, well-known method can easily be applied to petroleum samples. The technique will be discussed in detail as well as the components attached to a typical system. The ASTM and ISO methods, which reference this technique, will be illustrated. The fuel and other petroleum specifications will be discussed relative to the inclusion of these methods in the specification.

Multi-Element Analysis of Petroleum Crude Oils using ICP-MS

Jenny Nelson - Agilent Technologies

In the petrochemical industry, certain analytes are known to impact the performance and value of the final product. Consequently, there are several ASTM methods on the elemental analysis of oils, lubricants and fuels. One example is standard test method ASTM D7111-15a for the determination of trace elements in middle distillate fuels which uses Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). This method is widely used in the industry, but as specifications for fuels become more stringent, some laboratories are favoring the more sensitive analytical technique of ICP-MS, which provides significantly lower detection limits than ICP-OES. To reflect this trend, the first ASTM ICP-MS method for petroleum has been balloted in D0203. This is likely to be followed by an ICP-MS method for petroleum crude oils. This presentation describes how the Agilent 7900 ICP-MS was used to analyze different types of crude oil samples following simple dilution in an organic solution containing o-xylene. The aim was to develop a method that is suitable for routine use in the petroleum refining industry, particularly in high sample volume facilities, where turnaround time is critical. For this study, a wide range of samples were tested, and various quality control measures were taken. A series of 18 petroleum crude oil samples were used in the study. The chosen samples had a diverse set of properties; a wide range of American Petroleum Institute (API) gravity, elemental composition, hydrocarbon (H/C) content, and densities were selected. As a performance check, the 7900 ICP-MS was used to analyze diluted NIST 1634c standard multiple times per day with measurements taken over the course of a few months. The results show excellent recoveries for the certified elements V and Ni within + 10%, with good agreement. The recoveries for the non-certified elements As and Se in the SRM were within + 10%.

Simplified Method to Measure Performance Capabilities of Laboratory Analytical Instruments in the Oil and Gas Industry

George Gonzalez - Agilent Technologies
Dr. Raj Shah - Koehler Instrument Company

A simplified review method to measure performance capabilities for commercial analytical instruments is required. The energy and chemicals industry would greatly benefit from a reliable and straightforward statistically-based system which allows for determining the value-added performance of any test method. The proposed process and computational expression will determine the overall analytical performance value (APV) based on precision criteria relative to parameter measurements. The APV technique can then be used to compare any standard developed for testing the same parameter. Its numerical rating system will express performance measurements relative to two or more points within the operating value of each parameter featured in any standard method that exhibits full precision as defined by repeatability and reproducibility. In turn, this evaluation can justify the precision for between-laboratory testing in order to standardize the methods performed in an efficient way. Applying a more streamlined statistical approach such as the APV technique would assist laboratory personnel including managers, process engineers, chemists, technicians, and operators with its effects even reaching as far as commercial traders.

Laboratory Ventilation "More is Not Necessarily Better"

Karl Aveard LEED-AP - Gray & Green Laboratory Systems, Inc.

French philosophers say, "The wise do as much as they should, not as much as they can." Oversized HVAC systems in the hot humid climates of Texas and Louisiana are common. An attitude of "more must be better" equals system creep; pay me now and pay me later. This can be avoided with thoughtful and informed decisions during the early design phases. Those decisions include proper product selection; using excellent source capture with task specific devices, plus taking advantage of new and innovative technologies. Codes and best practices have evolved resulting in more GREEN approaches to earth friendly lab design. Selecting an experienced laboratory design team is paramount.

Coatings That Improve the Reliability, Stability and Performance of Sampling Systems used in Analysis of Ammonia and NOX Compounds

Gary Barone - SilcoTek Corporation

The last 15 years have shown an increasing need for coatings to improve analytical results obtained from systems used for mercury and sulfur sampling. As a result of increased regulation, sampling system performance must be rugged and stable, even in challenging and corrosive environments, while also reliable in order to meet frequent calibration inertness checks. To meet these stringent standards, the use of coatings has been specified or highly recommended. The data presented here will compare the stability of ammonia and NOx compounds on a variety of surfaces. Additionally, this presentation will address and summarize reports to-date on how coatings have been used to effectively improve the accuracy and reliability of sampling systems across several applications. Many industries have unique challenges that are solved by high durability, inert coatings that are designed to enhance chemical compatibility.

Process Raman Gas Analysis In Refining

Susan P. Harris - Endress+Hauser
Scott Sutherland, Ph.D. - SpectraSensors, Inc.

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.

How Scientific Companies use the Talent Supply Chain Management Model to Link Human Capital to Business Needs to Increase Productivity and Efficiency

Harvey Yau - KellyOCG
Jeff Garvin - KellyOCG
Linda Stuit - KellyOCG

Just like the conventional supply chain management, talent supply chain management model (TSCM) is an adaptable process of mobilizing and engaging resources on an as-needed basis, creating a lean, streamlined system of input and output. Because it offers oversight as to where talent is sourced, how it's engaged, and how it performs, TSCM allows companies to align their talent strategies with organizational objectives, optimize their workforces, and maximize the potential of their human capital-all while minimizing superfluous and inefficient processes. And by engaging vendors and labor in a manner that's in line with organizational goals, TSCM in effect creates an integrated or holistic system in which each part of the supply chain supports the rest. TSCM offers companies significant competitive advantages, including: • Enhanced workforce planning. • Oversight. • Predictive capability. • Risk mitigation. • Access to a broader talent pool.

Learning Objective 1 To teach attendees how to use the TSCM model to minimize risk associated in human capital when outsource project work: Risk mitigation. TSCM provides complete oversight as to sourcing and deployment of talent. At the same time, it yields data about quality. This enables companies to establish robust IP protection and risk mitigation policies and processes that are integrated with those of their vendors. Learning Objective 2 Workforce Planning Training. The issue is often overlooked. We will present the most effective and creative way to manage attendees' organization's talent asset by evaluating all possible sources of talent in a holistic manner and knowing how to engage workers, companies are better equipped to make sound decisions that are aligned with their overall objectives. We will also cover talent strategy that provides data about the deployment and performance of talent. When carefully analyzed and measured against industry best practices, it facilitates the fine-tuning of strategies to better meet organizational objectives Learning Objective 3 We will cover the advantages to manage projects and different work functional areas with Statement of Work strategies. The "SOW" strategy has been adopted by many leading scientific companies globally. We will also provide examples how the engineered workforce management models can be tailored to the specific needs of core or non-core functions of laboratory or scientific operations. The strategy has been adopted by many leading biotechnology, pharmaceutical, environmental consulting, chemical, energy and other companies in various other sectors to achieve tangible results in the functional areas of analytical testing, stability sample management, lab management, QA/QC Support, chemical inventory & maintenance and animal husbandry services.

A New Approach to Process Spectroscopy

Brian Rohrback - Infometrix, Inc.

Spectroscopy is great for monitoring and controlling process conditions in chemical plants and refineries. After all, the only way you can measure chemistry in a process is to utilize either spectroscopy or chromatography. Other than sampling system issues, the next most time-consuming activity for FTIR, FTNIR, or Raman is to construct and maintain the calibration of those instruments. After studying what we needed to do to build and manage optical calibrations in 20 different settings over the last 5 years, we have hit on a procedure that is independent of both hardware and software and constitutes the best practices for calibration. This leads to a significant reduction of cost, approaching 80%, for both installing and maintaining a process spectrometer.

More on the Unique Selectivity of Ionic Liquid GC Stationary Phases

Len Sidisky - MilliporeSigma
Greg A. Baney - MilliporeSigma
James L. Desorcie - MilliporeS
Michael Halpenny - 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.

FoamDDI - Fast, Reliable and Unbiased Determination of Foaming Tendencies of Lubricants by Digital Detection Imaging.

Aaron Mendez Ph.D. - Ayalytical Instruments, Inc #1218

The production, transportation, and processing operations in the oil industry are negatively impacted by the loss of efficiency of lubricating systems. Lubricants degrade overtime due to loss of viscosity, oxidation, polar and water contamination and foaming tendency. These phenomena are addressed by ASTM D892 that empirically rates the lubricants by determining its ability to resist foam formation and dissipate foam creation, however D892 is operator-biased, lengthy and produce low repeatable and reproducible results. Air is ubiquitous in lubricants so, when it is not released effectively, foaming appears, causing machine failures like metal wear, cavitation of pumping equipment, and acceleration of the oxidation rate. The industry spends millions of dollars in lubricant reposition, additives usage and corrective maintenance. Foam inhibitors eliminate or retard the formation of stable foam; however, it is a challenge that demands precise selection of the defoamant agents and careful control of its optimum concentration. The effect of antifoams and accurate measurement of lubricant properties requires continuous and fast response tests. Foam Digital Detection Imaging Apparatus (FoamDDI), can easily provide for fast, unbiased, and reliable results for foam stability and foaming tendency of lubricants.   FoamDDI consists of a system for sample conditioning, it is equipped with a high-resolution CCD camera, and a reader unit which possesses a state of the art optics and the VISION algorithm for accurately determining static and dynamic foam heights. The high precision and accuracy of the test lies in precise control of temperatures, air flows and sequences, it follows strictly D892 and is characterized by a minimal operator’s sample manipulation and the elimination of the critical timing involved in the manual assessment. Results show high repeatability and reproducibility. The automatic system produces simultaneously plots, pictures and videos allowing to follow the effect of antifoaming agents, the process dynamics and the quality of lubricants.

Flow-Modulated GCxGC for Routine Characterization of Petrochemicals

Matthew Edwards - SepSolve Analytical
Lara McGregor - SepSolve Analytical
Nick Bukowski - SepSolve Analytical
Bob Green - SepSolve Analytical

While GC×GC has been heavily adopted in R&D labs, it is rarely applied for routine analyses.  The thermal modulation devices which have dominated GC×GC literature require a cryogen fluid to modulate volatiles in the C4-C8 range – meaning additional running costs and extra hassle. Here we discuss a new commercial design of flow modulator, based on proven reverse fill/flush dynamics and demonstrate proof of performance with a variety of detectors.


Simple yet effective data processing will also be demonstrated, proving that GC×GC can be a productive member of any high-throughput laboratory, by enabling sophisticated data navigation and streamlined workflows.

Halogen and Sulfate Determination in Liquefied Petroleum Gas Using Combustion Ion Chromatography

Carl Fisher - Thermo Fisher Scientific
Adelon Agustin - COSA Xentaur
Mark Manahan - COSA Xentaur

Combustion ion chromatography (CIC) can measure trace halogens and sulfur (as sulfate) in non-water soluble solids and semi-solids such as organic solvents, plastics, polymers, and petroleum liquids. In liquefied petroleum gas (LPG) these components need to be quantified for transport, product specifications, possible corrosion sources, and to determine scrubber capacity for maintenance. This presentation describes the determination of total fluorine, chlorine, sulfate, and bromine in LPG using an automated approach to combustion sample preparation in combination with ion chromatography to deliver results with excellent accuracy and reproducibility, while eliminating the tedium of manual combustion methods.

Simplified CO and CO2 Analysis From <100 ppb to 100% Without Methanizer Poisoning

Andrew Jones - Activated Research Company

Let’s face it, methanizers can be troublesome to work with. Their nickel catalysts can degrade over time, influencing sensitivity and calibrated response factors, and catalyst refills are made difficult by hardened fittings and components. In this talk we discuss recent advances in catalytic reactor technology that give methanizers a much needed boost in robustness, linear range and ease of use. We demonstrate the unparalleled 7 order of magnitude linear range and sensitivity of the proprietary two-step Polyarc® reactor for carbon monoxide (CO) and carbon dioxide (CO2) analysis with GC/FID. We also show how the Polyarc® system can improve system stability and allow for the analysis of dissolved gases (DGA) in harsh transformer oils (TOGA) and other samples that prove troublesome for traditional methanizers.

Automated Freezing Point of Avgas

Larry Spino - PAC LP

The importance of measuring accurate freezing points of jet fuels is well known in our industry. Even for experienced operators, getting good results using the manual freezing point method, D2386, can be challenging; light quality can play an important role in locating the end point. Most automatic freezing point instruments do an adequate job finding the freezing point, but the very fine crystalline structure of some fuel types can elude detection except for the most sensitive automatic detection methods or the highly-trained eye using manual methods. This presentation compares a manual D2386 test set up and an automated laser-based freezing point instrument.

Optimization of Gas Chromatography by Inlet Liner Selection

Timothy Anderson - Phenomenex
Ramkumar Dhandapani - Phenomenex

GC inlet liners can be nearly as important to good chromatography as column selection. Much attention is given to GC columns; their phase selectivity, so-called “Fast GC,” inert and low-bleed varieties. Columns are routinely the primary component discussed when reviewing method development. However, analysts often overlook the much needed, yet forgotten GC inlet liner. This talk will review the importance of GC liners and demonstrate how given the same GC instrument parameters and column, very different chromatographic responses can be achieved by using different liners. We will also explore inlet optimization parameters that are very important to consider while optimizing GC method.

Speciation and Quantitation of Silicon in Petroleum Products Using 3rd Generation AED Coupled with Gas Chromatography.

Chen-Shi Huang - JAS (Americas) Inc.
Waldemar Weber - JAS GmbH
Joachim Gerstel - JAS GmbH
Dieter Kauczok - JAS GmbH

JAS has developed 3rd generation AED with new electronic boards and CCD detector. The new CCD detector without moving parts can reach 100Hz for data acquisition which makes it suitable for GCxGC applications. For Si ddtection, elimination of oxygen as a reaction gas has shown a significant reduction of diatomic emission and improvement in Si to C selectivity and thus the detection limit. Due to the geometric limitation,  Si 222 lines were used instead of Si 252 line. While the intensity of Si 222 line is only ~20 to 25% of Si 252, we have found that the detection limit of Si in a gasoline sample can reach ~ 0.1 ppm for each peak.

In this paper we will present the design and applications using the newly designed AED coupled with Gas Chromatography for the analysis of Si in petroleum products such as gasoline and diesel. The effects of data acquisition rate, reaction gas and GC conditions on the selectivity and detection limit of Si by AED as well as the linear dynamic range of Si will be reported.

Can Calibration Standards be Eliminated in Gas Chromatography?

Charlie Spanjers - Activated Research Company

Calibration standards have long been in engrained in gas chromatography analyses. Using standards is not only time-consuming but also costly, especially for gas standards and for rare molecules. More importantly, calibration standards add an additional source for error, reducing the reproducibility of methods. In this talk, we describe a method for identifying and quantifying unknowns in a single injection using a parallel Polyarc/FID and mass spectrometer (MS). Examples will be shown for the analysis of hydrocarbons and oxygenates for applications such as isoprene and butadiene synthesis, and methanol to gasoline chemistry.

Tracing Sources of CO2 with Delta Ray

Magda Mandic - Thermo Fisher Scientific

Stable isotope analyses provide a powerful tool to trace the fate of CO2 in the subsurface. Stable isotopes of injected CO2 can act as useful tracers in carbon capture and storage (CCS) because the CO2 itself is the carrier of the tracer signal and remains unaffected by sorption or partitioning effects. Laser spectrometers used in the field can help to improve our under-standing about processes in the subsurface. With this results we are increasing the applicability of reservoir safety and monitoring programs. Newly developed Thermo Fisher Scientific instrument Delta Ray Isotope Ratio Infrared Spectrometer (IRIS), for continuous stable isotope monitoring was used at the Ketzin pilot site in Northern Germany. We used it in order to get new insights into underground geochemical processes and subsurface migration of the CO2 plume.

Total Nitrogen in LPG by Combustion and Chemiluminescence

Aaron Mendez Ph.D. - Ayalytical Instruments and TSHR
Arthur - TSHR

The quality specifications for hetero elements in crudes and products mention particularly and entirely sulfur, excluding nitrogen. All reasons of quality, pollution, corrosion, detrimental impact on the economy of catalyst conversion processes and the like, can also be attributed to nitrogen compounds. The N analysis is gaining attention because at normal concentrations N compounds compete with S in hydro desulfurization processes effecting process efficiencies.

Analytical methods for the quantitation of nitrogen are varied and all face some challenges because nitrogen compounds exhibit different chemical properties, other basic and many are amphoteric, posing a challenge on the calibration standard selection, on the experimental conditions and in method development. Combustion reduces all these species to a single NO that reacts with Ozone in a selective and fast chemiluminescence reaction giving limits of detection in the order of ppb. We have tested several calibration standards with different N compounds and results prove that the method is selective, sensitive with a high degree of repeatability and reproducibility. The LPG automatic inlet system can inject samples up to 100 loops, producing a linear, high dynamic range calibrations utilizing a single compressed gas calibration matrix.

Subtle differences in polymer formulations are common, but they may not influence the overall performance of the final product.  However, there are instances where the product will suddenly be more brittle, easily deformed or fail in routine use. Detailed analyses of the good and bad polymer will often reveal differences in the additives and/or the presence of unwanted contaminates or unexpected chemical linkages. Pyrolysis techniques with GC/MS, as well as other selective detectors, will be used to characterize the differences between two rubber samples submitted for failure analysis.  Multiple pyrolyzer modes will be used to achieve a more detailed sample characterization.

Characterization of Organic Micropollutants in Ship Ballast Water by LC- High Resolution Accurate Mass Spectrometry

Noelle DeStefano - Duke University

Globalization of commerce has led to increased reliance on shipping, and as a byproduct, the translocation of 3-10 billion tonnes of ballast water per year. Water taken onboard during ballasting operations is expected to resemble that of the port surface waters, the quality of which is dependent on local pollution conditions. Organic micropollutants may be introduced into ballast waters through contamination of port water and directly from shipboard operating procedures. These compounds are discharged during the voyage into open ocean waters or within another port during de-ballasting operations. Thus, the potential exists for introduction of micropollutants to pristine waters as well as exchange and transport among global ports. To understand the chemical micropollutant burden of ship operations, ballast water and paired port water was sampled from ships in the USA, South Africa and Singapore. The water was characterized for the presence of polar organic compounds by Thermo UltiMate 3000 liquid chromatography system coupled to Thermo Orbitrap Lumos high-resolution accurate mass spectrometer. This presentation will discuss the results of this study as well as the advantages of applying LC-HRAM spectrometry for non-targeted analysis of complex environmental matrices.

Jonathan D. Byer - Byer Precision Machining

Petroleum products are often complex mixtures that require significant time spent on data processing to make sense of, whether classifying hydrocarbon classes or determining the distribution of compounds with different functional groups. Just collecting the data may take one software, with processing it taking another, and then bringing that information into a visually pleasing plot or diagram that makes sense from at a holistic point of view taking yet another different software package, all making it difficult to link the conclusions that characterize a sample back to original analytical data. With advances in ChromaTOF-HRT software, multi-dimensional chromatographic samples with high-resolution, accurate-mass spectra collected with either electron ionization (EI) or chemical ionization (CI) can be easily viewed with chromatograms, mass spectra, Kendrick mass defect plots, van Krevelen plots, and more all within one program. The ability to select a mass defect series based on C#, calculate probable formulas, and then elucidate structure by correlating back to the structured two-dimensional chromatogram with deconvoluted spectral comparison to commercially available libraries allows for quicker and more powerful assignment of peaks. Characterization of complex samples becomes simple, and visualizing the differences between samples can be done with side-by-side comparisons of commonly used plots, coded to highlight specific heteroatomic species of interest containing sulfur, nitrogen, or oxygen.

Fast GC relies on a combination of short capillary columns, high gas flows and rapid column heating.  While the technologies of making columns and delivering high flows are now common, fast heating has seen several manifestations.  A new approach to fast capillary column heating has recently been introduced.  A low mass heating disk is directly pressed against a conventional column wound in a planar form factor. The low thermal mass also provides faster cooling.  The performance of this fast GC will be demonstrated using several applications such as simulated distillation and environmental hydrocarbon contamination.

Reducing Mogas Octane Giveaway Via On-line Raman Spectroscopy: A One Year Case Study

Lee Smith - Process Instruments, Inc.

Reducing octane giveaway within a refinery is an ongoing battle, where the difference between the specification and the measured property directly effects refinery profitability. Octane rating is heavily influenced by butane, aromatic, and olefin levels. Optimizing octane levels within the refinery has to be performed using existing blend stocks that can change daily, and balanced against government regulated properties for Reid Vapor Pressure (RVP), aromatic, and olefin content. Raman spectroscopy offers unique, well defined spectral peaks for key octane enhancers such as alkylate, butane, aromatics, olefins, and oxygenates.  This helps explain Raman’s ability to accurately measure octane in gasoline. Incorporating state-of-the-art PLS chemometric modeling in a hierarchical approach allows refiners to optimize model performance throughout their seasonal blends.  Incorporating our Raman online monitoring technology has allowed one Chevron oil refinery in Richmond, California, producing 240,000 barrels per day (bpd) to save > $3,000,000 annually in octane giveaway.

Determination of Olefins in Condensates and Upgraded Bitumen by Gas Chromatography (GC) using a Vacuum Ultraviolet (VUV) Detector

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

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.

Low Level Fatty Acid Methyl Ester (FAME) Analysis of Aviation Fuels by FTIR Spectroscopy

K. Cory Schomburg, Ph. D. - PerkinElmer, Inc.

Middle distillate fuels such as kerosene and diesel routinely contain Fatty Acid Methyl Esters (FAME) that is blended to produce biofuels. These fuels are generally transported and distributed to and from various facilities using the same methods as aviation fuel. During this distribution there exists the possibility of contamination of the aviation fuel due to residual FAME in the distribution chain. FAME in fuels can be measured by FTIR spectroscopic techniques using EN 14078 and ASTM D7806. In this presentation a variation of the ASTM D7806 standard method is used to determine the low level FAME concentration in aviation fuels.

Comparative Evaluation of “Carbon Centric” Gas Chromatography Detectors for Volatile Organic Compounds (VOC) Analysis

Francois Huby - The Dow Chemical Company

VOC analysis is currently performed using gas chromatography as a measuring tool. The most common detectors are the Flame Ionization (FID) and the Mass Spectrometric (MSD) detectors. Both detectors require calibration using analytical standard solutions at known concentration of each detected compounds. For complex samples preparing these standard solutions, calibrating the chromatographic system and processing the samples chromatograms can be time consuming and costly. Carbon centric detectors directly measure the mass of carbon corresponding to each chromatographic peak. Knowing the chemical compound nature of the eluting compounds, possibly by using a spectroscopic detector, enables a direct unbiased estimation of the mass of compound eluting of the column. In addition to delivering accurate VOC levels, such detectors also simplify both the calibration of the system and the data reduction step of the analysis. In this talk we will compare several “carbon centric” detectors in terms of performance, easiness of use and cost.

Combustion Analysis of Commercial Diesel Fuels Containing FAME by ASTM E537 and Pressure Differential Scanning Calorimetry (PDSC)

K. Cory Schomburg - PerkinElmer, Inc.

Within the ASTM literature there are several standards that can be used to explore the thermal stability of hydrocarbons under inert or oxidative conditions using Differential Scanning Calorimetry (DSC) instrumentation. Most of these standards also provide the option of performing the stability test under ambient or elevated pressure to reduce sample volatility and simulate performance conditions. Under selected conditions, the relative oxidative properties of fuels may be explored to find the combustion temperature at various pressures and the heat flow energy. For this presentation, the thermal stability and combustion analysis of biodiesel standards and selected commercial diesel fuels is explored following the ASTM E537 standard.

An Accurate, Sensitive Method Analysing Residue in Liquefied Pressurized Gas (LPG) by Thermal Desorption/Gas Chromatography

Leeman Bennington - PerkinElmer
Lee Marotta - PerkinElmer

As LPG is transported through pipelines, hoses, and tanks it comes into contact with many contaminants, potentially resulting in a heavy residue in LPG. This residue, when left unchecked, can harm seals, valves, and even engines. Understanding the composition of this residue is important to determine the source of problems. This ASTM method presents an accurate and precise technique, answering the question is there contamination, and if so, how much of this contamination is present at the necessary detection limits. This presentation will demonstrate the ability to speciate the hydrocarbon residue range between C6 through C44 in pressurized gas using sorbent tube technology, thermal desorption, and gas chromatography accurately.

Nano Volume Injector Valve for Fast and Ultra Fast Gas Chromatography Analysis

Stanley D. Stearns - Valco Instruments Co. Inc.
Martin Brisbin - Valco Instruments Co. Inc.
Huamin Cai - Valco Instruments Co. Inc.

For fast and ultra-fast GC analysis, injection is one of the most important processes. A narrow band start peak is essential for a high quality fast GC separation.  Commonly people use split injection to obtain a narrow band peak.  However, the split injection dilutes the concentration of sample, consequently reducing the overall method sensitivity.  The split injection may also cause a sample discrimination problem which will affect the accuracy of quantification.  Another sharp peak creation method is the use of cryogenic refocus technology, but it is only suitable for high boilers.  Partial volume injection or dual valves partial volume injection is another method  to achieve a narrow band sample peak, but the amount being injected is influenced by many factors, such as timing, flow, pressure, temperature etc. which negatively affects  the repeatability.  In this presentation, we will discuss the relationship between valve volume and peak broadening and show the results of using a nano volume valve for a fast and ultra fast GC injection system.  Since both internal volume and dead volume of the nano volume valve are really small (nL level) it can create sharp injection peaks without tailing.  By using this system, a methane peak with only 8 millisecond peak width at half height W1/2 has been achieved.  It only needs 2 seconds to complete separate C1 to n-C6 and BETX.

A GCxGC Valve Modulator with Hold-Release Primary Column Flow for Long Secondary Separation Time

Huamin Cai - Valco Instruments Co. Inc.
Stanley D. Stearns - Valco Instruments Co. Inc.

Valve modulators have been used for GCxGC separation for many years.  Compared to thermal modulators, it has the advantages of simplicity, low cost, and no low boiling point limit. However, the valve modulator usually has a short modulation period PM because it needs to maintain continuous primary column flow. Consequently, it is easy to cause peak wrap around.  In this presentation, we will propose a hold-release primary column flow method to increase secondary retention time.  This method uses a valve to make the primary column flow reverse, slow down, and stop during secondary separation.  In this way, it makes the sample stay in the primary column longer and gain more time for secondary separation.  By using this method, a 20-second secondary retention time or modulation period PM has been achieved with 100% transfer from primary to secondary. A longer secondary retention time can increase the secondary separation power, reduce the requirement of fast response detection, and perform a second dimension temperature program.

Systematic Approach for the Optimization of on-line Supercritical Fluid Extraction – Supercritical Fluid Chromatography – Tandem Mass Spectrometry

Paige Wicker, Graduate Research Assistant - The University of Texas at Arlington

On-line supercritical fluid extraction - supercritical fluid chromatography (SFE-SFC) is a relatively new tool in the arsenal of analytical chemistry. For effective operation of the instrument, many extraction and chromatographic variables require consideration. Although these variables are generally understood as they apply to the individual techniques, when the two techniques are coupled online, there is a fundamental lack of understanding of how the variables interact. Our goal is to establish a streamlined work flow for SFE-SFC-MS/MS method development using multivariate experimental design approaches for online sample preparation, analyte separation, detection, and quantification for use in environmental analysis.

How Big of an Analytical Toolbox is needed to Assess the Impacts of Unconventional Oil and Gas Development?

Doug Carlton, Project Manager - University of Texas at Arlington

Is unconventional oil and gas development safe? This seemingly simple question has spurred propaganda, debates, legislation, and research over the past decade or so. Early assumptions towards finding an answer would be scouring EPA and other regulatory methods for air and water analyses. Through the years, we have developed a handful of analytical methods for groundwater, air, and various solid matrices to account for these unique settings. Efforts to understand some settings has led to microbiome characterization in groundwater through analytical microbiology. These rapid and informative bacterial measurements may provide more answers in some settings than traditional VOC and heavy metal screenings.

Rapid, Green, At-Line Approach to the Determination of Hydroxyl Number in Polyols

Dr. Linda Kidder, Product Manager - Shimadzu Scientific Instruments, Inc.

The number of hydroxyl groups on a polyol, referred to as the hydroxyl number, is a critical quality attribute (CQA) in the manufacture of flexible polyurethane and other specialty polymers. As the physical properties of the final polyurethane product depend upon the number of urethane linkages formed via these reactive hydroxyl groups, the determination of the hydroxyl number is a key QA step in the manufacturing process.  The current industry standard procedure is a laboratory-based titration method using hazardous chemicals, not ideal for testing in process manufacturing where rapid determination is sought. Here, we demonstrate a spectroscopic approach using FT-NIR with Partial Least Square (PLS) regression for accurate and rapid determination of hydroxyl number in polyols. This spectroscopic approach requires no reagents or solvents, uses disposable sampling cuvettes, generates results in seconds rather than minutes (or hours) and can be place at-line. Data will be presented that highlight this approach, and a discussion of method development will be included.

Analysis of Polycyclic Aromatic Hydrocarbons in Petroleum Vacuum Residues by Multiple Heart-Cutting LC Using the Agilent 1290 Infinity 2D-LC Solution

Sue D'Antonio - Agilent Technologies

Polycyclic aromatic hydrocarbons (PAHs) were determined in a petroleum vacuum distillation residue using the Agilent Multiple Heart-Cutting (MHC) 2D-LC solution. The extract was analyzed in the first dimension by normal-phase LC. Well-defi ned fractions from this separation were stored in a set of sample loops, then transferred online to the second-dimension separation where the PAHs were separated from each other and from other sample constituents using reversed-phase LC on a dedicated PAH column. Detection was performed with diode-array detection (DAD) as the monitor detector after the fi rst dimension, and with fluorescence detection (FLD) after the second dimension. An additional column switching valve enabled backflush of the first-dimension normal-phase column to remove highly polar components. The Agilent 1290 Infinity 2D-LC solution enabled automated, selective, and quantitative analysis of the PAHs in the complex petroleum vacuum distillation residue sample.

Two Proposed ASTM methods on Elemental Analysis of Biodiesel and Crude Oil by Microwave Plasma Atomic Emission Spectrometry (MP-AES)

Jenny Nelson - Agilent Technologies

One of the latest atomic spectroscopic techniques for measurement of trace elements in biodiesel and crude oils is Microwave Plasma Atomic Emission Spectrometry (MP-AES). This technique can replace other atomic spectrometric techniques such as atomic absorption spectrometry (AAS), graphite furnace atomic absorption spectrometry (GF-AAS), and compliment inductively coupled plasma atomic emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS), which are widely used in the petroleum industry. Performing elemental analysis in locations where obtaining argon is a challenge for the petroleum industry. MP-AES technology is a suitable alternative for this industry. Although other atomic spectroscopic techniques mentioned above are used in the petroleum industry, ASTM D02.03 Committee on Elemental Analysis is currently working towards development of two standards. There is an immediate need to define and implement an ASTM standard that would describe a procedure for the determination of trace elements in petroleum products using MP-AES. This work will present the proposed method which describes, the multi-element determination of trace elements by MP-AES in biodiesel and crude oil. In this case, we used Premisolv or o-xylene to dilute the samples and standards and then added an internal standard of Scandium and Yttrium into each diluted sample.

Recent Advances: An Overview of Fast GC, Sensitive GC and Even Simply Faster GC than the Traditional

John Crandall - Falcon Analytical

Fast gas chromatography has been deployed “from the winery to the refinery to the wellhead” as previously reported at GCC.  The value of rapid response has been demonstrated in the lab, at-line, online and even by the roadside.  However, recent applications expand the technology even more to include product purity at the 99.99% plus levels.  Environmental applications using both direct injection and pre-concentration trapping have been used to achieve limits of detection downwards from the parts per million level to parts per billion and even parts per trillion.  Also, demand for higher resolution capability have been met with longer column possibilities up to 16 meters for a total of 32 meters with two modules.  This paper will be a visual overview of the expanded capabilities of fast GC since Gulf Coast Conference 2016.

Resolving the Conflict between Lab and Process Data

Carl Recchsteiner - CRechsteiner Consulting, LLC
Joe Perron - Falcon Analytical

The conflict between lab and process data has always existed because the process data doesn’t always match the lab data. The lab’s primary function is to validate and certify products and it is therefore the adjudicator should discrepancies in data arise. Consequently, if the two sources of information do not conform, the process side is required to make the necessary changes, corrections, and adjustments; hence the conflict.

This paper explores data results for petroleum fraction samples ranging up to C44 or 535 ºC end boiling point on a lab and a process gas chromatograph (GC) wherein the same hardware and methods were used. The two GC’s differ only in their sample introduction method. The paper will discuss the operational parameters and the differences in results from liquid syringe autosampler based inlets used in laboratories to rotary valve based inlets required in the process all leading to a fluid free calibration of the process GC.

Recent Advances for Chromatography Data Systems in Fast GC: Control, Data Fusion, Automation

George Schreiner - ChromPerfect

 Modern gas chromatography continues to advance not only from speed and the need for higher data rates but also to the use of more and new detectors.  Integration of analog and digital data from outside sources, sometimes called data fusion is also required.  And there is an ever increasing desire to automate operations, system suitability and even automated assessment of results.  The suite of software including Chromperfect the basic chromatography data system, Chromperfect Process Control the process GC automation and human/machine interface system and the Chromperfect Marker Trace application and of course communications to process control systems exemplifies response to these new market requirements.  Use of these tools and their interaction with other data and programs like Infometrix LineUp and InStep make the applications possible in the hands of the intended end users.

ACCUTRACE™ fuel marking technology is entering its second year of use in the UK and Ireland. The award-winning system, including the ACCUTRACE™ S10 marker and the CALIDUS™ MT roadside detector, has “virtually eliminated fuel laundering” in the UK according to the UK press. It is also reported that as much as $1 billion in road use taxes have been collected due to the deterrent provided by the marking and detection systems.  At low parts per million treat rates, this marker technology is highly cost-effective and is resistant to laundering methods practiced by criminals to launder low taxation fuels intended for farming, fishing, domestic heating, and construction. The ultrafast CALIDUS™ gas chromatograph (GC) is utilized as a roadside analyzer and offers advantages in speed, sensitivity and transportability.  Configured with two column modules, a heartcut valve, and dual FID detectors, separation via 2D GC delivers detectability down to low parts per billion (ppb).   In the UK and Ireland, this marker and detection technology led to a reduction in laundering plants discovered, a decline in illegal use of subsidized fuels, and a drop in waste products associated with fuel laundering.  In summary, this work will show the instrument performance and capability for analyzing ppb concentrations of chemical markers in fuel using a transportable, fast GC.

Identifying Authentic and Fraudulent Diesel Fuel by Fast GC Using Chemometrics

Brian Rhorback - Infometrix
Joe Perron - Falcon Analytical

Fraudulent use of off-road fuel can take many forms and is becoming a global problem.  One way of avoiding road use tax is laundering markers from off-road diesel as just reported.  A more subtle one is adulteration of fuel and labeling it as something that is not fuel.  For example, biodiesel levels can be used as a diluent or base oils added or even high boiling fatty acids have been detected.  Before delivery to retail outlets, product certificates are switched to label the material as diesel.  The economic impact is not only tax loss but over time these materials can have a very negative impact on the consumers’ engines.

This paper will show how ultrafast GC coupled with chemometric techniques are an effective roadside detection and deterrent system for this criminal activity.  The GC, the software and the database functions will be discussed as an economically and technically viable fast roadside solution to end this kind of fraud.

Optimizing the Interface between Supercritical Fluid Chromatography and Electrospray Ionization Mass Spectrometry

Michael O. Fogwill - Waters Corporation

Supercritical fluid chromatography (SFC) employs a compressible carbon dioxide-based mobile phase. Since the solvating power of the SFC mobile phase is directly related to pressure, there is a dramatic difference in mobile phase properties from the point of sample introduction to the point of detection in a SFC system coupled with mass spectrometry (MS). In order to maintain excellent peak shape and maximize sensitivity, both instrument design and method development must be optimized to account for this change in mobile phase solvating power. When properly optimized, SFC-MS provides a very sensitive and robust interface with performance on par with liquid chromatography mass spectrometry.  This presentation will outline optimization of the instrumentation and the tuning parameters for the SFC-MS interface. Troubleshooting techniques specific to SFC-MS will be discussed with application examples.

Fast Gas Chromatography using Heated Headspace Gas Autosampling Techniques: Polyethylene Pellets, Product Purity Analysis

Derrick Saul - Falcon Analytical

Sampling is often the most difficult part of an analytical method even for micro and Fast Gas Chromatography.  In some cases the analytes of interest cannot be separated and measured with a column system that can survive the balance of the sample matrix.  Purity analysis of Polyethylene Pellets is an excellent example.  The solution is to heat the pellets and drive the target analytes into the headspace gas.  The autosampler using a gas tight syringe can then sample and introduce the resultant sample into the GC.  This paper will describe the system and the methods developed for this analysis.

Daniel B. Milligan - Syft Technologies
Murray J. McEwan - Syft Technologies

High-penetration-rate drilling technologies present a challenge to current mud-gas analysis techniques: they are limited in either analysis speed and/or the range of compounds measured.  Selected ion flow tube mass spectrometry (SIFT-MS) is an analytical technique that detects and quantifies volatile organic compounds (VOCs) directly in air to part-per-trillion (ppt) concentrations within seconds. SIFT-MS uses multiple reagent ions to provide highly selective, quantitative analysis of wide range of hydrocarbons and other compounds of interest in this field.   In this paper, we present data for C1 – C11 hydrocarbons that were acquired in a field test of SIFT-MS instrumentation for mud-tank headspace analysis.

Murray J. McEwan - Syft Technologies

Petrochemical facilities frequently emit volatile organic compounds (VOCs) as part of their regular operations, but occasionally the levels at the boundary exceed regulatory levels, such as those imposed by EPA Method 325. These emissions are transient and therefore not well characterized by traditional techniques.  

Selected ion flow tube mass spectrometry (SIFT-MS) is an analytical technique that detects and quantifies VOCs and inorganic gases directly in air to part-per-trillion concentrations within seconds. High-speed SIFT-MS analysis provides continuous fenceline monitoring.  

This paper presents results of real-time fenceline monitoring of benzene and other VOCs at the boundaries of petrochemical facilities.

True Plug-and-Play Chromatography

Brian Rohrback - Infometrix
Scott Ramos - Infometrix

In applications like simulated distillation, multiple instruments can run the same method but slight differences in column and flow conditions make chromatograms not match the time axis from instrument to instrument.  Normally, this would require separate calibrations or even slightly separate methods for each instrument.  With chemometric alignment, these minor variations can be compensated for and identical methods be used, potentially even skipping the calibration step.  The idea is very powerful: that a small amount of software can be added to a chromatograph and have that addition open a true Plug-and-Play capability for the instrument/application.  Ostensibly, a company could keep a cold spare chromatograph in inventory.  When a process or lab unit goes down for any reason, the storage unit would be placed on-line and have its data be completely comparable to all previous runs on its very first injection without ever running a calibration step.  Alignment can also apply this procedure to the historical chromatographic data assembly, giving a consistent database ready to be mined. Of course, this conclusion holds for situations where the column and the method conditions are very similar.  But if this is the case, it may be possible to think of a chromatograph with the same supply and repair mindset more often reserved for temperature and flow sensors.

Zbigniew Krieger - Extrel CMS

Fast vent-gas analysis will be critical for EPA RSR compliance at refineries that rely on active additions of supplemental gas to maintain a Net Heating Value (NHV) over 270 BTU/scf in the combustion zone. Online, industrial mass spectrometers update NHV several times per minute and provide a continuous, full-composition analysis of flare gas samples, including speciated hydrogen. The analyzer is extremely resistant to high levels of H2S, and is often used to measure sulfurs in addition to NHV, for dual compliance with both EPA Subpart Ja and the RSR combustion efficiency regulations.

Vacuum Ultraviolet (VUV) Absorption Spectroscopy: a novel method in the forensic analysis of fire debris evidence

Adam B. Hall, Ph.D. - Northeastern University
Sarah Pina - Northeastern University
James Diekmann - VUV Analytics, Inc.
Tom Steen - VUV Analytics, Inc.
Paul Johnson - VUV Analytics, Inc.

This research interfaced a VUV Analytics VGA-100 VUV spectroscopy detector to an Agilent 6890N gas chromatograph. This detector allows for the generation of high quality absorption data between 125-240 nm by using coated reflective optics and a charge coupled device light path to assess absorption across the VUV spectrum. Spectral filters allow for class discrimination of hydrocarbon-containing compounds by providing enhanced visualization of unresolved chromatographic species. This is a distinct advantage, especially for characterizing complex hydrocarbons in petroleum-derived products such as gasoline. VUV Analytics VUV AnalyzeTM analysis software engine allows for easy peak identification, as well as analysis of mass and volume percent of compound classes and carbon number class within the analyzed fuel samples. The unique software and detection capabilities were utilized to assess VUV absorption spectroscopy as a viable method for distinguishing gasoline brands.   GC-VUV data for 0%, 25%, 50, and 75% evaporated samples was produced for numerous gasoline sources obtained from local stations to assess both neat and weathered samples. Mass percentages of carbon number classes were generated by VUV Analytics VUV AnalyzeTM software. The VUV PIONA+TM application software plug-in is optimized for gasoline analysis and utilizes proprietary retention index files to identify the mass percent of parafins, isoparafins, olefins, naphthenes, and aromatics (PIONA), as well as the mass percent of each carbon number class, i.e. the percentage of C6s, C7s, etc.   The generated data was evaluated to determine if the VUV PIONA+TM software could be used for brand differentiation based on carbon number class and associated spectral features. During this presentation, data will be shown highlighting differences of 2-15% in PIONA mass percentages for the same hydrocarbon classes of different brands. A detailed characterization based on mass percentages of hydrocarbon classes represents a new and exciting dimension in fire debris and ignitable liquid analysis for the field of forensic science.

Gas chromatography with vacuum ultraviolet detection (GC-VUV) has previously been used for PIONA characterization as well as select speciation of finished gasoline and gasoline blending streams, via VUV-PIONA.  VUV-PIONA is highly customizable in terms of speciation capability, depending largely on the underlying spectral library and how distinct the absorbance spectra are.  For example, members of the aromatic BTEX complex are routinely speciated along with bulk PIONA characterization.  We discuss extension of aromatics speciation to higher carbon numbers using VUV-PIONA.  One application of immediate importance is particulate matter index (PMI) calculation, for which aromatics speciation is particularly significant.  The potential for more accurate PMI determinations using GC-VUV is discussed.  Aspects of more general GC-VUV speciation of fuels in the context of detailed hydrocarbon analysis (DHA) are also discussed.

Simultaneous Simulated Distillation (CNS-SIMDIS) in crude oils: Determination of Hydrocarbon, Nitrogen and Sulphur species using Gas Chromatography

Marijn van Harmelen - PAC L.P. | AC Analytical Controls B.V.
Rob de Jong

Sulfur and Nitrogen are the most abundant hetero-constituents in fuels and process streams. To optimize refining operations, it is of primary concern to determine precisely where in the boiling range span of the processing streams these undesired species are present.   Simulated Distillation type gas chromatography with flame ionization detectors (FID) and chemiluminescence detectors (NCD/SCD) for Sulphur and Nitrogen offers quantitative and qualitative information for each species versus the boiling point of the sample. This information may then be used to improve processes and/or quality specifications. The system simultaneously produces boiling point distribution data simultaneously for the 3 channels over a maximum boiling point range from C10 – C90 and even crude oil samples with non-eluting fractions will be handled by the system.

New Approved Method for Measuring Halides and Sulfur in LPG Using Combustion IC – ASTM D7994-17

Jay Sheffer - Metrohm USA
Jay Gandhi, PhD - Metrohm USA

Production and refinement of liquefied petroleum gas (LPG) continues to grow in both the US and North America.  Corrosion in these refineries remains a great concern, as billions are spent annually on repairs and lost revenue.  Halides and sulfur can contribute to corrosion; therefore, their levels are closely monitored to ensure product quality and maintain operation of the refinery.  Combustion ion chromatography (CIC) is an excellent technique for measuring these impurities in LPG and is uniquely capable of quantifying each halide and sulfur individually and accurately.  A new standard test method, ASTM D7994-17, has recently been approved for measuring total fluorine, chlorine, and sulfur in LPG using CIC.   Approval of this method signifies the reliability of the technique and its acceptance by industry.   This presentation will discuss this new method, describe instrumentation and calibration, and present results obtained from real-world samples using this technique.

Saving time and money with Microwave-assisted Solvent Extraction (MAE) for petrochemical applications

Reynhardt Klopper - Anton Paar USA, Inc.

Over recent years, traditional solvent extraction methods such as Soxhlet or simple reflux heating have been replaced by modern, more efficient setups. Microwave reactors provide significant benefits compared to traditional extraction equipment. By supporting closed vessel heating the temperature can be increased above the boiling point of the used solvent. Subsequently both the extraction time and solvent usage is reduced drastically. Moreover, comprehensive parameter control and documentation ensures reproducibility and data quality. This presentation will highlight the advantages of MAE as applied to various sample matrices, including petrochemicals, plastics and biofuels. An example includes the fast and efficient extraction of polycyclic aromatic hydrocarbons (PAH’s) from bitumen.

This training course is ideal for persons currently testing asphalt with a Dynamic Shear Rheometer (DSR) and for those planning on adding a DSR to their lab in the future.  

The course will cover toe following areas:

  • History of the SHRP program and AASHTO T315 test method
  • Purpose and content of new asphalt test methods such as MSCR
  • Good laboratory practices for sound DSR measurements

Attendees will leave with a better understanding of what the DSR is indicating about their samples, important operational considerations, and how to prepare for AASHTO/AMRL certification for their DSR.

Anton Paar will have a Dynamic Shear Rheometer at their booth in the GCC exhibition for course attendees to experience.

ASTM Method D8071 uses gas chromatography (GC) with vacuum ultraviolet (VUV) absorption spectroscopy to determine hydrocarbon group types, and select hydrocarbons and oxygenates, in automotive spark-ignition engine fuels.  The uniqueness of VUV spectra enables individual compound deconvolution in complex gasoline samples, while similarity of spectra within a class permits easy totals reporting (paraffins, isoparaffins, naphthenes, olefins, aromatics).  GC run time for D8071 is 33.5 min, but can be dramatically shortened through simple method translation to as little as 13.5 min.  Fully automated data processing produces a compound and class report in under 60 sec.

Passive Monitoring – A Guide to Sorbent Tube Sampling for EPA Method 325

Nicola Watson - Markes International
Wade Bontempo - Markes International
Matt Edwards - Markes International

US EPA Method 325 has been developed to enable refineries to comply with the updated US federal regulation CFR 40, and requires monitoring of VOCs around the boundary of refineries. This involves two-week passive (diffusive) sampling onto sorbent tubes, followed by analysis by thermal desorption (TD) in conjunction with gas chromatography (GC), with analysis by mass spectrometry (MS) or other detection technique.

While benzene is the primary target compound, the sampling and analysis methodology can also be used to determine other VOCs, including butadiene, toluene, ethylbenzene, xylenes and other hazardous air pollutants (HAPs). This paper will explain the stepwise process of the method and discuss how innovative sampling and analytical instrumentation is used to fully comply with Method 325.

Sour Water Stripper Online Process Control

Gerhard Kirner - Metrohm USA

Sour water in refineries is a waste water which results of atmospheric or vacuum crude columns. Sulphides and Ammonium are typically components in this stream which needs to be removed before this water can be reused for other purposes. In sour water stripping towers the H2S and the N3 is removed by adding heat to the water and the gases are exiting the tower top. It is necessary for this stripping process that the usage of energy and additional chemicals have to be kept at a minimum to run this process efficient. Measuring the residual content of  H2S and Ammonia at the bottom of the stripping tower helps refineries to reuse water in a more efficient way and safe therefore money and resources. The new Process Analyzer of Metrohm measures these parameters fully automated and unattended so a 24/7 monitoring of the stripper and the most efficient control of energy and reagent dosing is ensured.

A study of sulfur-containing compounds in pre- and post-treated gas oil samples  

Determining the presence and amount of sulfur-containing compounds in petrochemical feedstock is a primary concern for refinery operations due to the potential negative consequences these compounds can have on downstream equipment and end product quality.  Several analytical techniques exist to selectively measure these compounds, but such techniques generally do not provide further qualitative information that may be desirable in determining chemical formulae or structures of the sulfur-containing compounds for investigative purposes.  In this work, qualitative evaluation by GC/MS of pre- and post-hydrotreated gas oil samples from a diesel hydroprocessing unit was performed with an Agilent 7890B GC system coupled to a novel, high resolution accurate mass 7250 GC/Q-TOF equipped with a low energy capable EI source.
