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.

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

A gas separation unit for the separation of carbon dioxide from air is proposed for use in a cyclic adsorption/desorption process and using a loose particulate sorbent material. Sorbent material is arranged in at least two stacked layers, and each layer comprises two sheets of a flexible fabric material which is gas permeable but impermeable to the loose sorbent material. The sheets are arranged parallel defining an inlet face and an outlet face, are arranged with a distance in the range of 0.5-2.5 cm, and are enclosing a cavity in which the sorbent material is located. Said layers are arranged in the unit such that the inflow passes through the inlet face, subsequently through the particular sorbent material located in the cavity of the respective layer, subsequently to exit the layer through the outlet face to form the gas outflow.

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

A vacuum chamber () for a direct air capture process and enclosing an interior space () for housing an adsorber structure () is given comprising a contiguous circumferential wall structure () along an axis (), which circumferential wall structure () in an axial direction is closed by an inlet and an outlet axial wall (), respectively. Both axial walls () comprise at least one closing stainless steel lid () allowing for, in an open position, gas to be circulated through the vacuum chamber () for passing an adsorber structure (), and, in a closed position, to close the interior space () and to allow evacuation of the interior space () down to pressure of 500 mbaror less.
