Abstract
A method of removing hazardous sulfur compounds, such as hydrogen sulfide and sulfur dioxide, from sour crude oil and sour natural gas. An aqueous composition of an amine oxide surfactant, and preferably a mixture of an amine oxide surfactant and enzymes, is mixed with the sour crude oil or sour natural gas. The surfactant reacts with the hazardous sulfur compounds to eliminate the evolution of the compounds from the crude oil or gas and the enzymes act to catalyze the reaction.
