Abstract: A space and energy saving adsorber unit comprising two adsorber beds arranged in a common housing. The upper adsorber bed, disposed essentially vertically, is contained by gas permeable vertical walls, thereby permitting gas to be treated in the horizontal direction. The second adsorber bed, located beneath the first bed, slopes downwardly from an upper apex with increasing distance from a vertical central axis and is also enclosed, at least in part, by gas permeable walls. During regeneration of the system where water might be condensed in the bed, the condensate flows out of the bed without damaging the adsorbent.

Abstract: An adsorber for the cleaning of air or natural gas by the removal of water as a first component and carbon dioxide and/or a hydrocarbon as a second component from the gas stream to be treated utilizes two distinct adsorber beds traversed in succession by the gas stream, at least one of these beds being vertically oriented so that the gas stream and the regenerating gas pass horizontally through it.
