    摘要: The device comprises at least one column 1 that is filled with a number of beds A.sub.n, whereby each bed A.sub.i is separated from the next bed A.sub.i+1 by a fluid distributor plate P.sub.i. Each plate is divided into a number of sectors P.sub.10, and P.sub.11, and each sector comprises at least two fluid distribution chambers CH.sub.i and CH.sub.j. Each chamber of the plate is connected to a transfer line LT.sub.i and LT.sub.j to the outside. Transfer line LT.sub.i, which is associated with chambers CH.sub.i of a distributor plate, is connected to transfer line LT.sub.j, which is associated with chambers CH.sub.j of the same plate, via a bypass line L.sub.i,j. The latter comprises means 14, 15, 16, and 17 for controlling and adjusting the flow rate of fluid that circulates there, such that each distribution chamber CH.sub.i is flushed by a fluid that is obtained from chamber CH.sub.j and that has approximately the same composition as that of the fluid that circulates through distributor plate P.sub.i at each of the chambers.
