Adsorber structure for gas separation processes

A device for separation of at least one gaseous component of a gas stream containing said at least one component as well as further different gaseous components, by using a bed of loose particulate adsorber particles contained in at least one sorbent particle volume, said gas stream entering the device at an upstream end thereof and exiting the device as a gas outflow at a downstream end thereof, said device comprising:

• at least two inlet channels as well as at least two outlet channels being in said sorbent particle volume,
• wherein the inlet channels and outlet channels are mutually intertwined at least partly to form a nested structure in said sorbent particle volume and wherein the inlet channels and outlet channels are arranged with respective principal axes all essentially parallel to each other,
• wherein said inlet channels have at the upstream end at least one inlet opening through which said gas stream enters the device, and being closed to airflow at the downstream end,
• wherein said upstream end and downstream end of the inlet channels are connected by one or a plurality of side walls circumferentially enclosing and forming said inlet channel in said sorbent particle volume;
• wherein said outlet channels are closed at the upstream end and have at the downstream end at least one outlet opening through which the gas outflow is exiting the device,
• wherein said upstream and downstream end of the outlet channels being connected by one or a plurality of side walls circumferentially enclosing and forming said outlet channel in said sorbent particle volume;
• wherein said side walls are permeable to the gas stream but impermeable for said loose particulate adsorber particles, and
• wherein, viewed along the principle axes of the inlet channels and outlet channels, the inlet channels and outlet channels are alternatingly arranged in both lateral dimensions so that said sorbent particle volume is confined by the interspace defined by adjacent side walls of inlet channels and neighbouring outlet channels and said sorbent particle volume surrounding the channels essentially circumferentially around said principal axes of the inlet channels and outlet channels,
• wherein the inlet channels are formed by inlet strainers and the outlet channels are formed by outlet strainers, and wherein the device contains at least four inlet strainers and at least four outlet strainers,
• wherein the interspace between all the side walls of the channels of the device forms one single contiguous interspace forming one single contiguous sorbent particle volume suitable and adapted to be filled with and emptied from the particulate adsorber particles in a state in which all the channels in the form of inlet strainers and outlet strainers, are mounted in the device.
