Title
(EN) FOULING ABATEMENT FOR COKER HEATERS
(FR) RÉDUCTION DE L'ENCRASSEMENT POUR ÉLÉMENTS CHAUFFANTS D’UNITÉ DE COKÉFACTION
Abstract
(EN)
A polymeric quaternary ammonium based antifoulant composition having a polyamine crosslinked reaction product of an alkylamine and epichlorohydrin; and at least one aliphatic alkylene diamine. A method of inhibiting fouling on structural parts of a system exposed to a hydrocarbon, the method providing adding an antifoulant composition to a hydrocarbon medium, wherein the antifoulant composition comprises a polyamine reaction product of an alkylamine and epichlorohydrin, and at least one aliphatic alkylene diamine.
(FR)
L'invention concerne une composition antisalissure à base d'ammonium quaternaire polymère ayant un produit de réaction réticulé de polyamine d'une alkylamine et d'épichlorhydrine; et au moins une diamine d'alkylène aliphatique. L'invention concerne également un procédé d'inhibition de l'encrassement sur des parties structurales d'un système exposé à un hydrocarbure. Ledit procédé consiste à ajouter une composition antisalissure à un milieu hydrocarboné, la composition antisalissure comprenant un produit de réaction de polyamine d'une alkylamine et d'épichlorhydrine, et au moins une diamine d'alkylène aliphatique.
