Abstract:
Trace metals in crude oil and petroleum products have several harmful effects and need to be monitored. The leading cause of aviation fuel thermal stability failures is attributed to metal traces. Typically, fuel is analyzed by ICP-OES in fixed laboratories using sophisticated equipment, expensive consumables, and time. We developed a compact fuel analyzer capable of quantifying trace elements, both in dissolved and micro-particulate form. LIBS enables rapid, direct chemical analysis and requires no sample preparation, no consumables, and does not generate acidic waste. We attained sub-ppm level sensitivity for 9 elements: vanadium, copper, magnesium, sodium, titanium, silver, aluminum, silicon and lithium. Detection limits of less than 2.5 ppm were obtained for nickel, iron, chromium and tin while the detection limit of lead was 14 ppm. The portability and the sensitivity of the prototype makes it a suitable candidate for real-time fuel analysis in the field.
