Rapid Method For Determining Sulphur And Vanadium In Petroleum Products By Non Dispersive X Ray Fluorescence PDF Download

"Sulphur and vanadium in petroleum fractions cause serious difficulties, especially when the fractions are used as fuels. Levels of these elements are regularly controlled during the refining of crudes and tars, such as Athabasca bitumen, which have high metal and sulphur contents. One objective of CANMET's Energy Research Laboratories is to develop a high yield process for upgrading bitumen and heavy oils. The experimental work is performed in a thermal hydrocracking pilot plant. More information on the concentration of various elements is required for a better understanding of the process. A rapid instrumental method to determine sulphur and vanadium simultaneously by X-ray fluorescence was thus investigated. This technique is currently being applied to the determination of sulphur. The possibility of determining titanium in addition to sulphur and vanadium was also investigated"--Introd., p. 1.
