The introduction of the gas turbine as a marine propulsion plant has brought to light fuel contamination problems due to the presence of certain metals at low concentration levels. These metals have been found to cause corrosion, and with it, attendant operational problems. The source of these contaminants may be found in the heavier distillate fuels used in the gas turbine in an effort to reduce overall operational costs. Since the metals of interest occur at levels below 10 ppm, they present unique analytical problems, particularly with vanadium, the effects of which are considered deleterious even at levels below 2 ppm. This paper discusses the specific problems encountered with vanadium analysis in heavy distillate fuels.
