Abstract

L'invention concerne un perfectionnement aux procédés de décantation Ce perfectionnement est caractérisé par le fait qu'il consiste à créer une barrière thermique dans la phase la moins chargée en produit à séparer. Cette barrière thermique est réalisée entre la zone d'introduction du mélange à décanter et la zone de sortie du liquide décanté lorsque le décanteur fonctionne en continu. Application à la séparation du catalyseur d'un mélange provenant d'une installation d'alkylation du benzène par l'éthylène.
