Abstract: In a modular gas-separating adsorber assembly, a pair of cylindric vessels, filled-in by a given amount of an adsorbing material (either a mainly adsorbing or a mainly adsorbing material) are always operatively assembled with a top plate and a bottom plate, the top and bottom plates being mutually coupled by tie rods, engaged in the plate corners, the bottom plates and top plates forming plate chambers and being operatively connected with the chamber formed by adjoining cylindric vessel, the plates having projecting fittings to be assembled with the plate chambers included in adjoining vessels.

Abstract: A gas flow absorber comprises an absorption vessel, having a vessel wall defining a cylinder including an absorption material, the cylinder having a cylinder wall bearing, at the bottom thereof, in a circumferential slot formed on a support plate including a channel therethrough a gas mixture flow is conveyed, the channel having a channel hole passing through an enlarged portion of the support plate, the enlarged portion being coupled to a flat chamber substantially extending through the overall extension of the vessel bottom, the chamber being covered by a disc-like body made of a sintered material.
