The present invention is a process to reduce the fouling of equipment for processing petroleum feedstreams. The Fouling is reduced by reducing the presence of peroxides and hydroperoxides in the feedstream. The steps of the process include mixing the feedstream with an aqueous phase containing a base and a phase transfer catalyst. The base reacts with the peroxides and hydroperoxides. The oil phase can then be further processed with minimum fouling of the equipment. The aqueous phase is recycled for reacting with fresh petroleum feedstream.
L'invention concerne un procédé visant à réduire l'encrassement d'équipements de traitement de flux de pétrole. On réduit l'encrassement en réduisant la présence de peroxydes et d'hydroperoxydes dans le flux. Le procédé consiste à mélanger le flux à une phase aqueuse contenant une base et un catalyseur de transfert de phase. La base réagit avec les peroxydes et les hydroperoxydes. On peut alors traiter davantage la phase huileuse, entraînant un encrassement minimal de l'équipement. La phase aqueuse est recyclée en vue d'une réaction avec un nouveau flux de pétrole.
