IASH 2019 will benefit anyone with a technical and scientific interest in the development, use, handling and storage of fuels. This is a unique event where delegates can meet with colleagues from around the world to discuss fuels issues that affect every country. A wide range of technologies relating to the stability and distribution of liquid fuels from the point of manufacture to end-use will be discussed.
IASH 2019 will be comprised of four full days of technical sessions with a separate Technical Poster / Exhibitor reception on Monday evening. A commercial exposition will run throughout the symposium.

A WORLD OF DIVERSE FUELS – LATEST NEWS FROM RESEARCH, TECHNOLOGY DEVELOPMENTS AND FIELD EXPERIENCES
Thursday, September 12th, 9:30am – 9:55am
Jet fuel specifications require the determination of aromatics. Early in 2018, a key component of the Fluorescent Indicator Dyed Gel needed to perform Test Method D1319 became unavailable. An alternative dye was substituted, but the reformulated dyed gel was later found to be unsuitable for the analysis of jet fuel, diesel fuel and gasoline samples. The manufacturer is working on a reformulated dye but it will not be available until well after 2019, if at all. ASTM Subcommittee J has been looking for alternative methods for the determination of aromatics in aviation fuels.
Gas chromatography vacuum ultraviolet GC-VUV technology has shown great promise in the determination of saturates, monoaromatics, and diaromatic content by carbon number in aviation fuels. A new ASTM standard test method is being developed to provide a suitable alternative to D1319.
The GC-VUV technique is currently used in the analysis of gasoline-range fuels (ASTM D8071). In the jet fuel range, saturates, mono-aromatics, and diaromatics all have distinct VUV absorbance spectra which allow them to be deconvolved from one another in a complex matrix. The GC-VUV method will analyze jet fuel in a 14-minute run and a 2-minute automated quantitation, reporting total saturates and aromatics comparable to D1319. In the same analysis, diaromatics (speciated by carbon number) are reported comparable to D1840.
This paper will summarize the GC-VUV technique and compare to existing jet fuel analysis methods of ASTM D1319, ASTM D1840, ASTM D5186 and ASTM D6379.

Fast Analysis of Middle Distillates using Gas Chromatography-Vacuum Ultraviolet Spectroscopy by Alex Hodgson, VUV Analytics
Middle distillates like jet fuel and diesel have strict requirements regarding aromatic content to reduce pollution and maximize engine life. The current referee method, ASTM D1319, is becoming unsustainable as remaining dye stocks wane. Current alternative methods include supercritical fluid chromatography (SFC) and high-performance liquid chromatography (HPLC).
Vacuum ultraviolet (VUV) spectroscopy is a relatively new GC detection methodology that can analyze jet fuel in less than 14 minutes and diesel in less than 20 minutes. Automated quantitation using time interval deconvolution (TID) can determine total mono- and di-aromatics for jet fuel and total mono-, di-, tri-, and tetra-aromatics for diesel.
Hydrogen and Nitrogen as Carrier Gas Alternatives to Helium: Gas Chromatography-Vacuum Ultraviolet Spectroscopy of Hydrocarbon Groups and Select Compounds in Gasoline-Range Samples by Ryan Schonert, VUV Analytics
ASTM D3606 (benzene), ASTM D5599 (ethanol, oxygenates), and ASTM D5769 (benzene, toluene, total aromatics) gasoline tests typically require three dedicated GC systems, all using helium carrier gas, which is in short supply. ASTM D8071-17, PIONA and oxygenates analysis with gas chromatography – vacuum ultraviolet spectroscopy (GC-VUV), allows benzene, toluene, total aromatics, and ethanol, as well as other parameters, to be accomplished on one GC in less than 35 min.
Helium use can be eliminated entirely by employing alternate GC carrier gases, such as hydrogen and nitrogen. This presentation will demonstrate how using GC-VUV for the analysis of gasoline-range samples.

With the December 2018 revelations that the dye used to carry out referee method ASTM D1319 for Jet Fuel analysis is no longer available; refineries and test labs are forced to look at alternatives for this analysis. Have you made an informed decision on how you will replace ASTM D1319? Are you concerned about the costs associated with moving to an alternative approach?
Recently ASTM D8267 was approved as a standard test method for jet fuel analysis. This method runs on the VUV Analyzer™ Platform for Fuels and has significant advantages over the currently available options. This webinar will provide a detailed overview of the operation and advantages of ASTM D8267 – The Standard Test Method for the Determination of Saturated Hydrocarbon, Aromatic and Di-aromatic Content of Aviation Turbine Fuels using GC-VUV. In addition to ASTM D8267, this webinar will introduce the VUV Analyzer Platform, which is currently used to run ASTM D8071 for gasoline analysis, and provide important details on accuracy, precision, and how laboratories can reduce analysis cost using this platform.
