ABSTRACT:
This is a separation process employing a column of adsorbent which is divided sequentially into at least three zones, adsorption, purification and desorption zones. A net fluid flow is maintained through the column with the adsorbent moving actually or in a simulated manner countercurrent with respect to the fluid. The feedstock contains the components to be separated with one component being more selectively adsorbed in the adsorption zone by the adsorbent than the other components. A desorbent fluid effects desorption of the more selectively adsorbed component in the desorption zone, however, if carried over into the adsorption zone with the moving adsorbent the desorbent impedes adsorption. The process employs a flush stream introduced at the upstream boundary of the desorption zone, with the desorbent introduced between the upstream and downstream boundaries of that zone, which flushes the desorbent from the adsorbent prior to its movement into the adsorption zone.
