Continuous process to separate colour bodies and/or asphalthenic contaminants from a hydrocarbon mixture by passing part of the hydrocarbon mixture through a membrane over which membrane a pressure difference is maintained thereby obtaining ä hydrocarbon permeate having a reduced content of colour bodies and/or contaminants, wherein at regular time intervals the pressure difference over the membrane is substantially lowered.
La présente invention concerne un procédé pour séparer en continu des corps colorés et/ou des contaminants asphalténiques d'un mélange d'hydrocarbures. Ce procédé consiste à faire passer une partie du mélange d'hydrocarbures à travers une membrane sur laquelle une différence de pression est maintenue, afin d'obtenir un perméat d'hydrocarbures qui présente une teneur réduite en corps colorés et/ou en contaminants, cette différence de pression sur la membrane étant sensiblement réduite à des intervalles de temps réguliers.
