Title (EN) METHOD OF SEPARATING CONDENSED LIQUID FROM AN OLEFIN STREAM
(FR) PROCÉDÉ D'ISOLEMENT D'UN LIQUIDE CONDENSÉ À PARTIR D'UN COURANT D'OLÉFINES
Abstract: front page image
(EN)This invention is to a process for separating condensed water and entrained solids from an olefin stream so that fouling of the separation equipment by the entrained solids is reduced or eliminated. The process involves injecting an antifouling agent into a water condensing or quench system in an amount to maintain a zeta potential of fouling liquid and a zeta potential of the surface of the quench system both in a positive range or both in a negative range.
(FR)La présente invention concerne un procédé d'isolement d'eau condensée entraînant des particules solides à partir d'un courant d'oléfines de façon à ce que l'encrassement du matériel d'isolement par les particules solides entraînées soit réduit ou éliminé. Le procédé implique l'injection d'un agent anti-encrassement dans un système de condensation d'eau ou de trempe en quantité suffisante pour maintenir le potentiel zêta du liquide favorisant l'encrassement, comme de la surface du système de trempe, dans un intervalle positif ou dans un intervalle négatif.
