Abstract
High sulfur crude oil is desulfurized by a low temperature (25.degree.-80.degree. C.) chlorinolysis at ambient pressure in the absence of organic solvent or diluent but in the presence of water (water/oil=0.3) followed by a water and caustic wash to remove sulfur and chlorine containing reaction products. The process can be practiced at the well site for the recovery of desulfurized oil used to generate steam for injection into the well for enhanced oil recovery.
