Fuel Analysis: Water Detection in Jet Fuel, Diesel Fuel, and Gasoline

Fuel analysis is very important part of the refining process. By continuously monitoring the free water and suspended solids in fuels, operations can immediately detect inefficiencies or failures in filters, coalescers and separators and possible contamination from other sources.

optek scattered-light turbidimeters are being used at refineries, before distribution, at pipelines (both receiving and delivery terminals), and at airports before final loading. Proven optek performance, reliability and repeatability also make it possible to use these systems in remote and unattended areas.



Fuel Analysis: Water Detection in Jet Fuel, Diesel Fuel, and Gasoline Benefits

  • Inline, Real-Time, Continuous Fuel Quality Monitoring
  • Continuously Documented Quality Assurance Records
  • Reduced Sampling and Laboratory Analysis
  • Reduce/Eliminate the Possibility of Fuel Contaminants Causing a Catastrophic Equipment Failure

Water in Jet Fuel Detection

There are numerous potential contamination sources along the process, particularly for jet fuel since it is very hygroscopic. Nominal limits for free water in jet fuel are in the range from 1-15 ppm while other fuels may tolerate larger ranges. An optek dual beam scattered-light turbidimeter will immediately detect contamination of less than 0.5 ppm. This important measurement is accomplished in-line, in real-time, and designed for harsh and hazardous area classifications.

Fuel Filtering / Coalescing Contamination

Water and suspended solids are removed during the production, transportation and loading of fuel. Despite these process controls, potential contamination sources still exist. An optek dual beam scattered-light turbidimeter placed after a filter or coalescer can detect a failure or filter break immediately. Contaminated fuel can be diverted into a holding tank for further processing while uncontaminated fuel is moved down the process.
