1. A separation unit for separating at least one gaseous component from a gas mixture containing that component,
wherein the separation unit comprises:
at least one contiguous and sealing circumferential wall element, circumferentially enclosing at least one cavity,
said at least one contiguous and sealing circumferential wall element defining an upstream opening and an opposed downstream opening of said at least one cavity, said cavity containing at least one gas adsorption structure for adsorbing said at least one gaseous component,
wherein the separation unit further comprises a pair of opposing sliding doors for sealing the upstream opening and the downstream opening, respectively, of at least one cavity in a closed state, and
wherein each of the pair of opposing sliding doors, to open the closed cavity, is shifted in a direction essentially parallel to the plane of the respective sliding door to uncover the upstream and downstream opening, respectively and to allow for flow through of gas mixture through the gas adsorption structure,
wherein the separation unit contains an array of at least two cavities with circumferential wall elements enclosing the cavities and each housing respective gas adsorption structures, wherein said pair of opposing sliding doors is mounted to allow for alternatingly sealing one cavity of the separation unit as well as the other cavity(ies),
and wherein the separation unit is attached to or encompasses only one common evacuation unit, or only one common heating unit, or only one common collection unit for the gaseous component, or only one common drive at the upstream side and the downstream side for the doors, or only one set of louvres at the upstream side, in each case common for all cavities, while for each cavity an individually controllable gas or air propelling device is provided at the downstream side.
