Title (EN) CONSERVING FRESH WASH WATER USAGE IN DESALTING CRUDE OIL
(FR) CONSERVATION DE L'UTILISATION D'EAU DE LAVAGE FRAÎCHE DANS LE DESSALAGE DE PÉTROLE BRUT
Abstract:
(EN) Methods for conserving the use of fresh wash water in crude oil desalting are described. A crude oil stream including salt mixes with a wash water stream to form an emulsion. The emulsion flows to a desalter, and the wash water coalesces to reform the wash water stream and to transfer at least a portion of the salt from the crude oil stream to the wash water stream. The crude oil stream with reduced salt content separates from the wash water stream. The effluent, which includes the wash water stream, flows from the desalter to a processing unit. The effluent is processed to reduce a concentration of salt in the effluent to be substantially equal to or less than a concentration of salt in the wash water stream. At least a portion of the processed effluent mixes with the crude oil stream before the emulsion flows to the desalter.
(FR) L'invention concerne des procédés de conservation de l'utilisation d'eau de lavage fraîche dans le dessalage de pétrole brut. Un flux d'huile brute comprenant un sel se mélange avec un flux d'eau de lavage pour former une émulsion. L'émulsion s'écoule vers un dessaleur, et l'eau de lavage fusionne pour reformer le flux d'eau de lavage et transférer au moins une partie du sel du flux d'huile brute vers le flux d'eau de lavage. Le flux d'huile brute ayant une teneur réduite en sel se sépare du flux d'eau de lavage. L'effluent, qui comprend le flux d'eau de lavage, s'écoule du dessaleur vers une unité de traitement. L'effluent est traité pour réduire une concentration de sel dans l'effluent pour être sensiblement égale ou inférieure à une concentration de sel dans le flux d'eau de lavage. Au moins une partie de l'effluent traité se mélange avec le flux d'huile brute avant que l'émulsion ne s'écoule vers le dessaleur.
