Abstract: Improved desulfurization compositions are provided for removing substantial fractions of sulfur, sulfur complexes, and sulfur compounds from liquid hydrocarbons such as crude oil and fuels. The preferred compositions comprise amine adducts, such as the adduct formed by reacting benzoic acid and a fatty acid amine. The compositions may be contacted with liquid hydrocarbons in the presence of water to achieve high levels of desulfurization. Preferably, the compositions are added substantially continuously to a flowing stream of liquid hydrocarbon and water, e.g., to the output from a producing oil well or in pipeline transmission and/or refinery equipment.

Abstract: Improved desulfurization compositions are provided for removing substantial fractions of sulfur, sulfur complexes, and sulfur compounds from liquid hydrocarbons such as crude oil and fuels. The preferred compositions comprise respective quantities of an alkylphenol ethoxylate, an amine, and an alkali metal nitrite. The compositions may be contacted with liquid hydrocarbons to achieve high levels of desulfurization.
