Background

The quality and grade of crude oil in part depends on the metal content as well as the sulfur content. Nickel and vanadium are the critical metals, as well as iron in some crudes and in residual oils and the metal content is especially important in the quality of bunker fuels.

ASTM D8252 addresses the need to measure low levels of nickel and vanadium in crude to meet the new NYMEX/CME specifications for light sweet crude oil futures contract concerning maximum allowable levels the Ni and V.

To meet the needs of the industry, Rigaku offers the NEX QC+, a simple, versatile, and portable benchtop EDXRF analyzer for the analysis of sulfur in crude, residual oil and marine fuels.
