[54] DESULFURIZATION OF WHOLE CRUDE OIL BY SOLVENT EXTRACTION AND HYDROTREATING
[57] Abstract: A high sulfur content crude oil feedstream is treated by mixing one or more selected solvents with a sulfur-containing crude oil feedstream for a predetermined period of time, allowing the mixture to separate and form a sulfur-rich solvent-containing liquid phase and a crude oil phase of substantially lowered sulfur content, withdrawing the sulfur-rich stream and regenerating the solvent, hydrotreating the remaining sulfur-rich stream to remove or substantially reduce the sulfur-containing compounds to provide a hydrotreated low sulfur content stream, and mixing the hydrotreated stream with the separated crude oil phase to thereby provide a treated crude oil product stream of substantially reduced sulfur content and without significant volume loss.
