ABSTRACT:
The invention is a column for separating a substance from a liquid having a plurality of separable compounds. The column has at least a first and a second bed of granular solids separated by at least one device, the device has at least a collection device which collects the substance to be separated, the collection device being in fluid connection to at least one mixing chamber, at least a first circuit for injection and/or removal of a first secondary fluid B.sub.1 and at least a second injection and/or removal circuit of a second secondary fluid B.sub.2. The injection and/or removal circuits are in communication with the mixing chamber with at least one opening allowing passage of the secondary fluids B.sub.1, B.sub.2 into the mixing chamber. The mixing chamber has at least one inlet orifice and at least one outlet orifice, and a device which redistributes the fluid coming from the mixing chamber, wherein the injection and/or removal circuits are separated and disposed in a vicinity of the mixing chamber along at least one wall of the chamber that has a direction substantially parallel to the device axis.
