Abstract:
A device suitable for chromatographic separation by a simulated moving bed of a feedstock, said device comprising at least one column (1) that is filled with an adsorbent, whereby the column comprises a number of beds (A.sub.n) and a fluid distributor plate P.sub.i between each bed, each distributor plate is divided into a number of sectors, and each sector comprises at least two fluid distribution chambers (CH.sub.i, CH.sub.j) that are pierced with orifices (18) and a fluid circulation space (8) near said orifices of the chambers, all of chambers CH.sub.i of a plate and all of chambers CH.sub.j of the same plate are connected respectively to a transfer line LT.sub.i and a transfer line LT.sub.j that extend between the chambers and a point that is located outside of the column, wherein transfer line LT.sub.i, which is associated with distribution chambers CH.sub.i of a plate Pi, is connected via a bypass line L.sub.i,j to transfer line LT.sub.j, which is associated with other distribution chambers CH.sub.j of this same plate Pi, and wherein the bypass line comprises means (15) for controlling and adjusting the flow of the fluid that circulates there.
