Abstract
A system and process for desulfurizing a hydrocarbon feed stream containing organosulfur compounds is provided. In general, the system includes a conventional hydrotreating unit through the high pressure cold or hot separator. Aqueous oxidant and an oxidative catalyst are mixed with the hydrotreated hydrocarbon effluent from the high pressure cold or hot separator, and oxidative desulfurization reactions occur in the low pressure separation zone, thereby minimizing or eliminating the requirement of additional oxidative desulfurization reactors.
