Abstract
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.
