Long Beach, CA

16th International Conference on Stability, Handling & Use of Liquid Fuels

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.

Aromatics and Diaromatics in Jet Fuel by Gas Chroamtography Vacuum Ultraviolet Detection – A New ASTM Method

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.
