Title:
PROCESS FOR GENERATING AND REMOVING SULFOXIDES FROM FOSSIL FUEL
Document Type and Number:
WIPO Patent Application WO2004099348
Kind Code:
A3
Abstract:
Processes for generating and removing oxidized sulfur species, and in particular sulfoxides, from crude oil and various fractions derived therefrom. Initially, the sulfur species present in the crude oil or fractions derived from the crude oil, is oxidized such that substantially all of the sulfur species are converted to sulfoxides and/or a combination of sulfoxides and sulfones. Thereafter, the fossil fuel containing the oxidized sulfur species are subjected to conventional hydrodesulfurization processes where substantially all of the sulfones are converted to hydrogen sulfide gas.
