ABSTRACT:
A system comprising a cylindrical housing containing a sorbent cartridge selective of one or more gases in a gaseous mixture. End caps on opposite ends of the housing seal to the ends of the cartridge and direct the flow of gas mixture through a portion of the cartridge. The first end cap has entrance and exit ports for the gas mixture and for a purging gas for cartridge regeneration. The second end cap includes a compartment to receive and return the gas mixture to the first cap exit port. The purging gas follows a similar pathway via the remaining portion of the cartridge. The cartridge is rotatable within the housing; thus, the exhausted portion of the medium may be rotated into position for regeneration while a regenerated portion of the medium is rotated into position for re-use, thus providing continuous adsorption from the gas mixture.
