Abstract

See full text

A process for purifying a hydrocarbon feed, using a first adsorption unit with first and second adsorption columns respectively filled with first and second adsorbent solids by simultaneously:

    a) treating the liquid phase hydrocarbon feed in the first adsorption column by contact with the first adsorbent solid to adsorb at least a portion of impurities present and to produce hydrocarbon effluent which is depleted in impurities;b) treating a secondary liquid hydrocarbon feed constituted either by a fraction of the hydrocarbon feed or by a fraction of the hydrocarbon effluent and depleted in impurities to purify the secondary liquid hydrocarbon feed;c) heating the treated secondary liquid hydrocarbon feed from step b);d) regenerating the second adsorbent solid of the second adsorption column which comprises impurities with the secondary hydrocarbon feed heated in step c) to desorb the impurities to produce an effluent with impurities.
