PRESSURE SWING GAS SEPARATION ABSTRACT A pressure swing gas separator is operated with a pressure difference between its presurised and depressurised states of less than 0.1 bar. Preferably it operates at a repetition frequency greater than one cycle per second and preferably between 50 and 200 cycles per second. Preferby the pressure swing gas separator includes a bed of adsorbent material (16, 108, 147) and forms part of a resonant system. Means (1, 101, 140, 141) are included operating at the resonant frequency of the resonant system, to pressurise and depressurise the bed of adsorbent material (16, 108, 147) so that the pressure energy of the desorbed gas mixture is substantially recovered. The means may include a tuned diaphragm (109, 133, 141) adjacent but spaced from one face of the bed of adsorbent material (16, 108, 147), driving means (1, 101, 150) arranged to drive the diaphragm (109, 133, 141) at its resonant frequency towards and away from the bed of adsorbent material (16, 108, 147), valve means (110, 115, 131) to introduce a gas mixture to and exhaust a depleted gas mixture from, a space between the diaphragm (109, 133, 141) and the bed (16, 108, 147), and a gas outlet (112, 113, 149) in communication with the other face of the adsorbent bed (16, 108, 147). In use, the movement of the diaphragm towards and away from the adsorbent bed pressurises and depressurises it.
