Abstract
A gas separation system for separating a feed gas mixture into a first component of the gas mixture and a second component of the gas mixture includes an adsorbent bed assembly and an axial or centrifugal compression machine. The adsorbent bed assembly includes a number of flow paths for receiving adsorbent material therein for preferentially adsorbing the first gas component in response to increasing pressure in the flow paths in comparison to the second gas component. Each flow path includes a pair of opposite ends and a valve communicating with each opposite end for controlling a flow of the feed gas mixture through the flow paths. Preferably, the compression machine consists of a gas turbine including a number of pressure inlet and outlet ports coupled to the valves for exposing each flow path to a number of different pressures between an upper pressure and a lower pressure for separating the first gas component from the second gas component.
