A structure for the adsorption/desorption of a substance on a bed through which liquid is allowed to pass, wherein the structure comprises: a) a vessel (1) which contains a liquid-permeable bed (2); b) a bottom adaptor (3) which (A) is placed in the lower part of the vessel and defines the vessel bottom and (B) has an opening (4) for the inlet/outlet of liquid to/from the lower part of the vessel, wherein opening (4) also has a distributing function (5) directed towards the bottom; c) an upper adaptor (6) which (A) is placed in the upper part of the vessel and (B) has an opening (7) for the outlet inlet of liquid from/to the upper part of the vessel, wherein the opening (7) is directed towards the bed (2) and it has a distribution function (8) in the same direction; and d) means (23, 24) for connecting the flow of liquid to the adapters (3, 6) or for conducting the flow of liquid away from the adapters (3, 6). In accordance with the invention, the upper adaptor is able to move vertically in the vessel and has a density which allows the adaptor to float on liquid passing through or present in the column.
On décrit une structure permettant l'adsorption/la désorption d'une substance sur un lit à travers lequel on fait passer un liquide, laquelle structure comprend: a) un réservoir (1) contenant un lit perméable aux liquides (2); b) un adaptateur inférieur (3) qui (A) est placé dans la partie basse du réservoir et constitue son fond et qui (B) possède un orifice (4) permettant l'admission/l'évacuation d'un liquide vers/depuis le fond du réservoir, lequel orifice (4) a également un système de distribution (5) dirigé vers le bas; c) un adaptateur supérieur (6) qui (A) est placé dans la partie supérieure du réservoir et qui (B) possède un orifice (7) permettant l'évacuation/l'admission d'un liquide depuis/vers la partie supérieure du réservoir, lequel orifice (7) est dirigé vers le lit (2) et possède un système de distribution (8) dans la même direction; et d) des moyens (23, 24) permettant la circulation de liquide vers ou depuis les adaptateurs (3, 6). Selon l'invention, l'adaptateur supérieur peut se déplacer verticalement dans le réservoir et possède une densité lui permettant de flotter sur le liquide traversant la colonne ou se trouvant à l'intérieur de celle-ci.
