ABSTRACT:
A thermodynamic pressure swing adsorption cycle utilizing "loudspeaker" diaphragms or pistons which are located at the top and bottom of a column containing a bed of adsorbent. The diaphragms are vibrated out of phase with each other so as to provide a displacement wave in the gas mixture within the bed of adsorbent. In addition to this displacement wave the gas is compressed prior to upward displacement and the gas pressure is lowered before the downward displacement by way of a second set of "loudspeakers" which form the side walls of the column. The second set of loudspeakers vibrate in phase with each other and operate at the same frequency as the displacement speakers.
