*KEYNOTE SPEAKER* Compact Analytical Instrumentation in the Petroleum and Petrochemical Industries: Portable Liquid Chromatography as an Emerging Technology

Dr. Milton Lee - Axcend, Provo, UT, and Brigham Young University, Provo, UT

A major trend in the analytical chemistry field today is to significantly reduce the size of analytical instrument components and products. Reduction in size generally allows greater mobility, simpler operation, lower cost, and greater productivity. These characteristics are especially important in the petroleum and petrochemical industries because of the broad-ranging needs for timely chemical measurements in some of the most diverse locations. Taking the instrument to the sample instead of the sample to an instrument that is permanently located in a laboratory makes much more sense in these industries compared to many others. Liquid chromatography (LC) has been slow to embrace compactness and portability compared to spectrophotometry and gas chromatography (GC), for example. Today, new developments in materials and hardware components have accelerated efforts to develop compact LC. In the last few years, truly portable gradient LC has become commercially available, offering small high-pressure pumping systems that can deliver microliter to nanoliter/min mobile phase flow rates, fittings and transfer lines that minimize dead volumes to preserve chromatographic performance, and multiple detector options including single wavelength on-column UV-absorption detection with LED light sources, multi-wavelength diode array detection (DAD), fluorescence detection and, of course, mass spectrometry (MS). Small diameter (< 0.3 mm i.d.) packed capillary columns can be pre-mounted in temperature-controlled, easy-to-connect cartridges that literally take less than a few minutes to install/exchange. Examples of applications that are particularly well suited for compact LC in the petroleum and petrochemical industries include point detection of hazardous chemicals in emissions and effluents, chemical process monitoring and optimization, purity assessment of reclaimed process water, determination of final compositions of petroleum products, measurement of additive levels in petroleum-derived fuels, and detection of fuel marker compounds. The extremely low mobile phase flow rates characteristic of portable/compact capillary LC minimize the cost and bother of purchasing and disposing of mobile phase solvents, and clearly position the technique in the elite class of “green analytical chemistry.”

*KEYNOTE* Activities of The NELAC Institute (TNI) to Improve Data Quality

Jerry Parr - The NELAC Institute

Part 1:  How a Quality Management System Improves Data Quality and Laboratory Performance Since its inception, individuals active in the US National Environmental Laboratory Accreditation Program (NELAP) have struggled to try and find information to convince others that implementing a Quality Management System (QMS) according to the requirements in the TNI Standard Management and Technical Requirements for Laboratories Performing Environmental Measurements improves data quality.  Over the years, various surveys and studies have been conducted to try and prove this assertion.  However, the problem has been, and always will be, we never know the true concentration of a contaminant in a sample.  All measurements are only estimates of the true concentration, and quality control data does not always directly correlate with the measurement of the actual contaminant. In 2019, TNI’s Advocacy Committee initiated a new effort to document improved laboratory performance and trust in the data provided by accredited laboratories.  This presentation will summarize the outcomes from the Committee’s efforts and provide real examples of why implementing a QMS based the TNI standard makes a real difference in both data quality and laboratory performance.

Part 2:  Evaluating the Goodness of Instrument Calibration for Chromatography Procedures Instrument calibrations in analysis methods using gas chromatography (GC) or liquid chromatography (LC) are usually created using either average response factor (RF) or linear (sometimes quadratic) regression equations. The quality, or “goodness,” of an Average RF calibration is measured by relative standard deviation (RSD) whereas the linear regression has historically been measured by correlation coefficient (r) or coefficient of determination (r2). This presentation will demonstrate that the goodness of a calibration measured by RSD is quite different than r/r2 and that while one is suitable as a calibration measure, the other is not. Relative standard error (RSE) is a way of extending the use of relative measures of calibration quality beyond the average RF calibration type.

THURSDAY SESSION * Aviation Fuels - An Overview

Roger Gaughan - ASTM International

The one-day Aviation Fuels training session is intended to be an introduction to the three-day course usually taught in other scenarios. IT IS NOT A SUBSTITUTE FOR THE THREE-DAY COURSE TAUGHT IN VARIOUS LOCATIONS OR IN ON-SITE TRAINING BUT WILL BE A GOOD INTRODUCTORY SESSION. For specific employees, ASTM suggests that key personnel attend the three-day course. This applies to all who work in the aviation field because only then can you have the necessary redundancy that is required, even if you are in manufacturing, distribution, testing, purchasing, into plane agents or aviation customers using the fuels.

Subjects to be discussed include: 

  • A general review of tests used at the manufacturing location for Aviation Turbine Fuel and Aviation Gasoline.
  • A brief discussion on engine parameters which can be affected by aviation fuel properties.
  • Key properties that affect the performance of aviation fuels.
  • A general summary of the downstream testing (beyond the point of manufacture) to the airplane. Aviation fuels are tested extensively in the points downstream of manufacture and this session will only summarize those.
  • A brief description of field quality assurance measures used by the aviation industry.
  • The instructor for this course have had extensive experience in the aviation fuels industry.

Abstract # 107 - Paper

The comprehensive evaluation of Source Rock using Micro-Furnace Multi-Shot Pyrolysis GC/MS

Athena Nguyen - Frontier Lab Americas
Rojin Belganeh - Frontier Lab Americas

The increasing world population and the expanding world economy have precipitated a rush to find new sources of energy for developing new oil and gas sources. Exploration today often relies upon the geochemistry of the source rock from the play of interest. The importance of Rock Evaluation Pyrolysis and the presence of specific compounds or groups of compounds in source rock is of immense importance to industries engaged in assessing the potential of a given play. Although many laboratories continue to solvent extract the sample prior to analysis, others have found that thermal extraction of the source rock will often yield a faster more accurate determination of the organic content. In this presentation, the comprehensive evaluation of Source Rock was performed using micro-furnace Pyrolysis-GC/MS with eliminating the need for conventional sample preparation.

Raman for Closed-Loop Process Control

Brian Rohrback - Infometrix, Inc.

 Much effort has been applied to put process spectrometers to work for a specified application:

  • Selecting instrument settings for best performance;
  • Automating method development for wavelength selection and preprocessing; and
  • Automating calibration updates.

At this point, there is only one task that remains for us to close the loop and completely automate the lifecycle of a Raman analyzer for any given purpose.  We need to identify when a calibration requires attention and then have a system in place to institute an adjustment without supervision.  Introducing a process Raman should be no more difficult to manage than installing a temperature sensor.

Use of Thermo Scientific Trace GC for ASTM D2887B Accelerated Procedure with Alternative Carrier Gases

James Pachlhofer - Thermo Fisher Scientific

The world is experiencing yet another helium supply crisis.  ASTM International recognized this fact several years ago and requires that analytical methods up for renewal be tested using alternative gases by their ILS process so the alternative gases may be to be certified for use with the method. D2887B is the accelerated procedure method for this important simulated distillation method.  This accelerated procedure has been utilized for several years using helium carrier gas. Recently, an ILS was performed to certify hydrogen and nitrogen carrier gas together with helium to be acceptable carrier gases. Data will be presented and discussed using a Thermo Scientific Trace GC to demonstrate compliance to D2887B for the three carrier gases.

A Fresh Approach to D5769 Analysis using a Thermo Scientific ISQ7610 Single Quadrupole GCMS

Amit Gujar - Thermo Fisher Scientific
Kenneth Free - Thermo Fisher Scientific
James Pachlhofer - Thermo Fisher Scientific

D5769 for Benzene, Toluene and Total Aromatics in Finished Gasoline by Gas Chromatography/Mass Spectrometry is the ‘gold’ standard method required for certification of gasoline in many countries and regions of the world.  The method challenges detection limits as well as linear ranges of the components of interest in GCMS.  Also, as changes in the composition of gasoline continue to evolve, this further challenges the GCMS instrumentation to comply with the method. The new Thermo Scientific ISQ7610 MS together with the new 1610 GC provides a fresh approach to overcoming these challenges.  The new Extended Dynamic Range Electron Multiplier used in the ISQ7610 provides the range necessary for the method without compromising any required MS hardware or operational parameters. Data will be presented and discussed demonstrating full compliance to the method using the Thermo Scientific GCMS.  All aspects of the method specifications including sensitivity, resolution, ion check tests, calibration, and reference material compliance tests will be presented.  In addition, the analysis of an ASTM D5769 ILS sample will be presented demonstrating excellent results.

Improved characterization of malodours from recycled plastics using TD–GC×GC–TOF MS

Matthew Edwards - SepSolve Analytical

The analysis of plastic has gained increased attention in recent years, due to the global push to move to a circular economy and use more recycled plastics, which require more rigorous quality control to ensure they will not produce harmful or odorous emissions.

However, there are several limitations with the existing methods for the detection of odours from plastics – such as, human sensory panels, eNose and GC-MS.

Here, we show how TD–GC×GC–TOF MS can address these challenges, by providing high sensitivity and improved separation of the odour profiles, prior to confident identification of the individual analytes.

Recent developmewnts and Validation of a More Accurate Tool for Fuel Clarity by D8148, Spectroscopic Method for Haze in Fuels

Ranzy Morgan - Choice Analytical Inc.

Recent Developments and Validation of a more accurate tool for Fuel Clarity by D8148 Spectroscopic method for Haze in Fuels   Providing fuel with the necessary cleanliness has been desirable since the earliest days of motorized transportation. Engine manufacturers expend significant effort to protect sensitive components of modern high pressure fuel systems from fuel contaminants. With an unprecedented number of new fuel types and feedstocks entering the worlds fuel supply, the industry is becoming increasingly concerned about fuel cleanliness and clarity. Over the decades, engine manufacturers, fuel producers and fuel distributors, worked within ASTM to establish specification limits for fuel haziness and clarity. Because of the variability and subjectivity found with the current visible methods such as D4176 and because ASTM specifications may be applied anywhere within the fuel distribution systems, fuel pipelines and transport companies have traditionally not supported these efforts. During the last five years, major pipelines have worked closely to support the optics-based technology found in D8148. ASTM D8148 Haze Clarity index is an instrumental objective technique which eliminates the subjectivity of the visual haze methods. D8148 measures and reports haze results in two formats 1) Instrumental Haze Rating (IHR) ranging from 1-6 which is calibrated to be equivalent to the D4176 Visual Haze rating, and 2) Haze Clarity Index (HCI) ranging from 50-100.  HCI provides greater resolution and specificity of fuel cleanliness.  With the large amount of data provided in the recent D8148 Interlaboratory Study, as well as CRC report 675, which compares D8148 to D4176 and actual amounts of water in fuel samples, it may be the time to seriously reconsider putting measurable limits around fuel cleanliness. This presentation will review the D8148 method, recent ILS results along with the data and conclusions presented in CRC report number 675.

In-line Naphtha Property Monitoring via Raman Spectroscopy

Giancarlo Aguirre - Process Instruments, Inc.
Lee Smith - Process Instruments, Inc.

The use of Raman spectroscopy for analysis of the various refinery products has increased dramatically in the last 20 years.  While ASTM Laboratory tests are still needed and are the gold standard in order to build such models, the need to constantly run them is less. This advantage can be expanded to the online monitoring of products such as Naphtha where this fraction is a key component of the gasoline blending process and/or feed of other units within the refinery.   Naphtha can be consistently separated into two fractions, light and heavy.  Ranging from C5/C7 for the light cut and up to C9 for heavy. Regardless of the Naphtha process, Raman spectroscopy can be an important tool to verify the unit targets and provide tight control off key properties.  It is also used extensively for distillates such as Jet and Diesel.   Throughout this presentation examples will be shown of the analysis Raman can be implemented for, with the aid of regression and classification type models along with corresponding laboratory test data. Examples of the instrumentation used in refinery settings along with feedback from active users will also be provided.   Raman has allowed unit operators to monitor and control their blends more effectively without having to invest in multiple individual property analyzers.

Optimizing Process Operations with On-Line Process Monitoring

Carl Fisher - Thermo Fisher Scientific

Industrial processes have common needs: reliable, accurate, and timely methods for analyzing process chemistry. Continuous monitoring with on-line liquid chromatography (LC) lets you detect process variations earlier than laboratory-based measurement and long before yield is impacted or costly process shutdowns become necessary. By improving process monitoring capabilities, you can fine-tune the process chemistry to maximize efficiency and reduce operating costs. Thermo Scientific™ Dionex™ Integral™ systems provide cost-effective, flexible solutions to apply on-line ion chromatography (IC) or high performance liquid chromatography (HPLC) to applications in a controlled setting, such as a laboratory or in a more challenging industrial environment. System modularity allows for the addition of modules and enclosures to tailor a configuration to meet specific needs. Several examples of how such systems have been applied to monitor waste and process streams will be presented.

How clumped isotope analyses drive a deeper understanding of petrochemical processes

Nina Albrecht - Thermo Fisher Scientific
Darren Tollstrup - Thermo Fisher Scientific

Classical stable gas isotopes, such as δD, δ13C, and δ18O, are well-established and valuable tools in various fields of earth sciences. They aid in constraining genetic mechanisms, provenance, transport processes, and formation temperatures. Their geothermometric usability is however limited as they lack an absolute temperature dependency. Clumped isotope geochemistry overcomes this limitation since the equilibrium distribution (‘clumping’) of heavy isotopes within multiply substituted molecules is solely dependent on the formation temperature.

The most investigated clumped isotope systems are clumping in CO2 and in CH4. It has been demonstrated that the associated thermometry delivers highly precise carbonate and methane formation temperatures. When two clumped isotopologues of one species are analyzed, it is even possible to pin down kinetic biases in cases where a sample is deviating from the expected thermodynamic equilibrium. Apart from geothermometry and the identification of kinetic processes, the addition of clumped isotope signatures to the classical stable isotope geochemist’s toolbox enables a refined forensic source apportionment of natural samples.

In this presentation we will illustrate the analytical setup (IRMS and HR-IRMS) to perform the above-mentioned measurements, and we will focus on how clumped isotopes add fresh insights into petroleum research. Besides CO2 and CH4, we will also give a perspective on the potential of clumped isotope analyses in N2, and H2, as typical compounds in natural gas reservoirs.

Unraveling the power of X-Ray Fluorescence technique for accurate quantitative analysis of Industrial materials

Poulami Dutta - Dow Chemical

X-ray Fluorescence (XRF) is an immensely powerful analytical technique for inorganic elemental analysis and is widely used in industry for different quantitative analysis needs including catalyst supports, promoters, polymer additives. Different categories of XRF instruments include high-end wavelength dispersive (WD) floor models to simple but rugged energy dispersive (ED) bench-top units. With recent advances in instrumentation and affordability, it is now possible to implement robust, accurate and precise EDXRF quantification methods in manufacturing laboratories that would traditionally require use of WD instruments available at a R&D lab only allowing on-site data acquisition for process control. It is also possible to use simple ED units to extract location-specific elemental distribution using benchtop Micro XRF instruments. Aside from instrumentation, sample preparation is critical for achieving high quality XRF data and accurate quantification. This workshop would be focused on highlighting different XRF technologies and sample preparation tools, highlighting practical examples of solving real life challenges.

Viscosity: Not all measurements are created equal: Shear rate, shear stress, shear range- oh my.

Irene Pena - Lummus Technology

Most simple viscometers provide information at a single point whereas rheometers examine behaviors of the fluid over a range of points producing a flow curve. Rheological measurements are by definition far more complex than kinematic or rotational viscometer measurements because they evaluate flow properties such as shear thinning, shear thickening, viscoelasticity, and even structural recovery. When we evaluate properties of this nature, even one’s technique will affect results.

This presentation will take a closer look at how varying techniques affect rheological measurements.

“FIDIG” - FID Ignition Guaranteed

Matthew Monagle - Advanced Industrial Chemistry Corp.

It has been the author’s experience, over many years, that the automated process of lighting an FID is often unsuccessful.  In this situation, it is necessary to invoke a process affectionately known by the author as “Puff the Magic Dragon” to get the detector to ignite.  FIDIG solves this problem.  A simple modification to an FID chimney results in consistent repeatable FID ignition.  Implementing FIDIG means that an FID will ignite without external assistance.  It also means the detector can be turned off when not in use and save significant amounts of air, hydrogen and make-up gas.
