Abstract # 100 - Paper

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

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

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.

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

Materials in the oil and petroleum industry scale a large range of viscosity and will be placed under wide ranges in shear rates within these applications. Having accurate measurements and data of these materials in order to mimic or predict their behavior will provide a benefit to the user. We will discuss how a microfluidic rheometer can be used to analyze materials with a wide range of viscosity and shear rates using only a single set of chips, typically in the range of four to five orders of magnitude for each measurement parameter.

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.

Abstract # 113 - Paper

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 beeen 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 esily abe 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 metods, which reference this technique, will be illustrated.  The fuel and other petroleum specifications will be discusssed relative to the inclusion of these methods in the specification.

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

Jenny Nelson - Agilent

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%.

Transferring Routine Lab GC Analysis to Automatic On-Line Measurement

Ulrich Gokeler - Siemens Industry Inc.

Continuously laboratory analysis is performed multiple times a day to support product quality and process control. By transferring those routine lab analyses to an automatic and on-line measurement system, there can be significant cost savings. Measurement point dependent, because higher measurement frequency and repeatable sample conditions possibly enable improved process and quality control.

This presentation will discuss the possible benefits of transferring laboratory GC measurements, especially pointing out considerations reaching from measurement focus to ROI.

Material Characterization – Extrusion techniques for Polymer and Crude Oil Industries

Steve Watts - Thermo Fisher Scientific

Small, lab-scale extrusion systems provide unique opportunities for material characterization and process development.  Formulation studies and a comprehensive understanding of a material’s processability can be realized and rapid process development for direct scale-up leads to improved efficiency due to increased time-to-results and reduced cost of materials.  In addition, the creation of sample products, whether injection molded specimens (discs or bars) or final product simulation (sheets, blown film), provides additional analytical opportunities and insight to the material’s properties.  Depending on the requirements, various types of systems can be used including micro-compounders, bench-top extruders and torque rheometers, and these will be discussed here.

Material Characterization – Rheology for Polymer and Crude Oil Industries

Steve Watts - Thermo Fisher Scientific

The petrochemical and polymer industries utilize rheology to better understand their materials and how they behave under controlled conditions. This allows users to gain insight into their processes and solve real-world challenges. Relevant applications would include the determination of physical properties (viscoelasticity, molecular weights and distribution, transition temperatures, extensional viscosity), processability (degradation, curing) and flow under extreme conditions (high pressure and temperatures). Here, we will discuss several methods that employ rotational rheometers, extensional rheometers and torque rheometers to address these challenges.
