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.
