Kind Code:
A3
Abstract:
A method of removing sulfur from sour oil by subjecting sour oil having a first sulfur content to high shear in the presence of at least one desulfurizing agent to produce a high shear treated stream, wherein the at least one desulfurizing agent is selected from the group consisting of bases and inorganic salts, and separating both a sulfur-rich product and a sweetened oil product from the high shear-treated stream, wherein the sulfur-rich product comprises elemental sulfur and wherein the sweetened oil product has a second sulfur content that is less than the first sulfur content. A system for reducing the sulfur content of sour oil via at least one high shear device comprising at least one rotor and at least one complementarily-shaped stator, and at least one separation device configured to separate a sulfur-rich product and sweetened oil from the high shear-treated stream.
