Title (EN) PROCESS FOR SEPARATING KINETIC HYDRATE POLYMER INHIBITORS
(FR) PROCÉDÉ DE SÉPARATION DE POLYMÈRES INHIBITEURS CINÉTIQUES D'HYDRATES
Abstract: front page image
(EN)Process for separating kinetic hydrate inhibitor polymers having a molecular weight of at least 1000 Da from an aqueous mixture further comprising hydrocarbons and salts which process comprises contacting the aqueous mixture with the feed side of a membrane having an average pore diameter of from 0.7 to 4nm, and obtaining at the permeate side of the membrane an aqueous permeate of which the concentration of kinetic hydrate inhibitor polymer is at most 20 % of that of the aqueous mixture.
(FR)La présente invention concerne un procédé de séparation de polymères inhibiteurs cinétiques d'hydrates ayant un poids moléculaire d'au moins 1000 Da d'un mélange aqueux comprenant en outre des hydrocarbures et des sels, ledit procédé consistant à mettre le mélange aqueux en contact avec le côté d'alimentation d'une membrane ayant un diamètre moyen des pores allant de 0,7 à 4 nm, et à obtenir du côté perméat de la membrane un perméat aqueux dont la concentration du polymère inhibiteur cinétique d'hydrates est au plus de 20 % de celle du mélange aqueux.
