Abstract
Pressure swing adsorption separation of a gas mixture is performed in first and second working spaces, with each working space having a flow path contacting adsorbent beds and variable displacement chambers. The volumes of the first and second working spaces are cyclically varied in opposite phase by oscillations of a liquid column whose movements change the volume of variable displacement chambers, so as to achieve cyclic pressure changes in each working space as required for the pressure swing process, while the inertia of the oscillating liquid column exchanges energy between the first and second working spaces.
