Abstract
The present invention is a process to reduce the fouling of equipment for processing petroleum feedstreams. The steps of the process include mixing the feedstream with an aqueous electrolyte forming an oil-in-water dispersion, passing the dispersion through an electrochemical cell, passing a low voltage current through the dispersion, and separating the phases of the dispersion. The oil phase can then be further processed with minimum fouling of the equipment. The water phase is recycled for dispersing fresh petroleum.
