Abstract

When petroleum (i.e. crude oil) is distilled, a residual fraction containing molecules that do not volatilize is drawn off the bottom. This “resid” has an increased concentration of minor impurities, including sulfur-, nitrogen-, and oxygen-bearing heterocyclics, soluble nickel and vanadium compounds and a variety of trace metals. These impurities both dominate the unique properties of the resid and play a major role in determining the refining processes necessary for its conversion to marketable products. This article introduces the common analytical techniques for the measurement of sulfur, nitrogen, nickel, vanadium, and trace metals in this challenging organic matrix.
