A gas separation unit for the separation of a first gas, carbon dioxide, from a mixture, by using an adsorption/desorption process using a loose particulate sorbent material arranged in at least two stacked layers. The primary heat exchange piping is arranged on the two outer edges of the layer within the cavity extending along a longitudinal direction. Further, an essentially parallel array of secondary heat exchange pipes is provided, the secondary heat exchange pipes extending along a transverse direction. The first diameter of the secondary heat exchange pipes is at least twice as large as the second outer diameter of the secondary heat exchange pipes and the secondary heat exchange pipes are in thermal contact with sheets of metal which extend oscillating between pairwise adjacent secondary heat exchange pipes.

Low-pressure drop structure of particle adsorbent bed for adsorption gas separation process

A gas separation unit for the separation of a first gas from a mixture containing said first gas as well as further gases by a cyclic adsorption/desorption process using a loose particulate sorbent material for gas adsorption. The particulate sorbent material is arranged in at least two stacked layers () that are mounted on a stiff rectangular circumferential frame (). A plurality of tubes () is provided for a heat exchange fluid within the frame (). The tubes () are in thermal contact with a plurality of sheets () of metal which are arranged essentially perpendicular to a main plane of the frame () and perpendicular to the tubes (). The sheets () extend in a continuous manner between a first pair of mutually parallel metal profiles (') and are provided with a plurality of holes () through which the plurality of tubes () penetrate.
