Abstract

The present invention describes a device for the distribution of fluids in a multi-stage column operating in simulated moving bed (SMB) mode comprising, in the direction of flow of the principal fluid, a distribution system (6) for auxiliary fluids, and a distributor plate (10) supported by stiffening elements (7) located below said plate (10), said device being interposed between two successive beds of granular solid (2) denoted the upstream and downstream bed, the distribution system and the stiffening elements being immersed in the upstream and downstream granular beds to a slight extent with an upper limit for the degree of immersion.
