Patent ID: 8496738

Claim:
A system for separation of a gas mixture and collection of at least one constituent gas, comprising in combination: a gas mixture inlet adapted to insert the gas mixture into said system; a gas compression element coupled to said inlet, said gas compression element having a high pressure side and a low pressure side, said sides of said gas compression element being reversible; an inlet valve between said inlet and said gas compression element, said inlet valve adapted to open and close access between said inlet and said gas compression element; a chamber on a side of said gas compression element opposite said inlet; said chamber including media therein which preferentially adsorb a target constituent gas more than other gases in the gas mixture; an exhaust valve on a side of said chamber opposite said inlet; a collection region; and a junction on a side of said gas compression element opposite said chamber, said junction adapted to at least partially divert gas from said chamber through said gas compression element to said collection region.
