Abstract
The device comprises at least one column 1 that is filled with a number of beds A.sub.n having an adsorbent that are separated by a fluid distributor plate P.sub.1. Each plate is divided into a number of sectors P.sub.10 and P.sub.11, and each sector comprises at least one fluid distribution chamber 13 that is pierced with openings and a circulation space 8 in the vicinity of the openings. The chambers of the plate are connected to a line 10 for transfer to the outside. With respect to the chambers on a plate, transfer line 10 P, is connected to another transfer line 20 relative to chambers 23 on another plate (P.sub.i+1 or P.sub.i+2) that is arranged downstream by a bypass line L.sub.1,2. The latter comprises means 14, 15, 16 for monitoring and adjustment of the flow of fluid that circulates there, such that the distribution chambers are flushed by a fluid which has approximately the same composition as that of the fluid that circulates through circulation space 8 at each of the chambers.
