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.
L'invention concerne un procédé visant à réduire l'encrassement d'équipements de traitement de flux de pétrole. Le procédé consiste à mélanger le flux avec un électrolyte aqueux, formant une dispersion huile dans eau, à faire passer cette dernière dans une cellule électrochimique, à faire traverser un courant de faible tension dans la dispersion et à séparer les phases de la dispersion. La phase huileuse peut alors subir un nouveau traitement, entraînant un encrassement minimal de l'équipement. La phase aqueuse est alors recyclée afin de disperser du pétrole neuf.
