The present application provides a method for reducing fouling, including particulate-induced fouling, in a hydro-carbon refining process including the steps of providing a crude hydrocarbon for a refining process; adding a polyalkyl succinic acid derivative additive. The additive can be complexed with a boronating agent, such as boric acid, to yield a boron-containing polyalkyl succinic acid derivative.
Cette invention concerne un procédé permettant de réduire l'encrassement, comprenant l'encrassement induit par des matériaux particulaires, dans un procédé de raffinage d'hydrocarbures. Le procédé selon l'invention comprend les étapes consistant à préparer un hydrocarbure brut pour un procédé de raffinage ; et à ajouter un additif du type dérivé d'acide polyalkylsuccinique. L'additif peut être complexé à un agent de boronation, tel que l'acide borique, pour donner un dérivé d'acide polyalkyluccinique contenant du bore.
