Title
(EN) METHODS FOR SEPARATING WAX PRODUCTS FROM HYDROCARBON FEEDSTREAMS
(FR) PROCÉDÉS POUR SÉPARER DES PRODUITS À BASE DE CIRE À PARTIR D'UNE CHARGE D'HYDROCARBURES
Abstract
(EN)
Disclosed are methods and apparatuses for separating a wax product from a hydrocarbon feedstream by a) conducting a hydrocarbon feedstream to a membrane separation zone; b) retrieving at least one retentate product stream from the first side of the membrane element; c) retrieving at least one permeate product stream having a wax phase and an oil phase from a second side of the membrane element, wherein a pour point of the wax phase of the permeate product stream is higher than a pour point of the oil phase of permeate product stream; and d) separating a wax product from the wax phase of the permeate product stream.
(FR)
L'invention concerne des procédés et des appareils pour séparer un produit de cire d'une charge d'hydrocarbure par a) conduire une charge d'hydrocarbure vers une zone de séparation de membrane; b) récupérer au moins un flux de produit de rétentat à partir du premier côté de l'élément de membrane; c) récupérer au moins un flux de produit de perméat ayant une phase de cire et une phase huileuse à partir d'un second côté de l'élément de membrane, un point d'écoulement de la phase de cire du flux de produit de perméat étant supérieur à un point d'écoulement de la phase huileuse du flux de produit de perméat; et d) séparer un produit de cire de la phase de cire du flux de produit de perméat.
