Abstract: A unit for purifying a gas mixture by adsorption, including at least one adsorber having at least one cluster of N identical adsorbent modules operating in parallel, where N?2, each cluster of N adsorbent modules includes a common inlet manifold having a straight inlet duct of axis Xe supplying N inlet nozzles Tei, where i ranges from 1 to N, respectively connected to the inlets Ei, where i ranges from 1 to N, of the N modules of the cluster, a common outlet manifold having a straight outlet duct of axis Xs collecting the flow leaving the N outlet nozzles Tsi, where i ranges from 1 to N, respectively connected to the outlets Si, where i ranges from 1, of the N modules of the cluster.

Abstract: An adsorber for purifying or separating a gas stream, wherein a granular-material filling system is made up of a cylinder that is perforated over all or part of its height, of the top end thereof of diameter Dext, and of the bottom end thereof. The distance Din-Dext is greater than twice the size of particles of the second granular material. A first granular material and the second granular material follow one another in the direction of circulation of the gas stream and are such that M>ADN. And, the second granular material is in contact both with at least a part of the outer surface of the granular-material filling system and at least a part of the inner surface of the domed top end.

Abstract: A device configured to be interposed between a lower layer and an upper layer of particles arranged inside a cylindrical shell, thereby limiting or preventing the migration of particles between the layers.
