The concentration of adsorbate in the feed gas to an on-stream bed of a cyclical swing adsorption process is monitored and the data processed to predict the time required to complete the on-stream mode of that bed and the purge flow rate and/or other regeneration mode operating condition of the concurrently off-stream bed is modified in response to changes in said predicted time whereby the regeneration mode of the off-steam bed is completed at the same time as the on-stream mode of the concurrent on-stream bed.
A cyclical swing adsorption process in which one adsorber bed is in an on-stream mode, during which adsorbate is adsorbed from a feed gas mixture passing through the bed, while another adsorber bed is in a regeneration mode, during which the adsorbed adsorbate is desorbed from the bed, and said beds alternate between said modes, wherein the time required to complete the on-stream mode is determined by the total amount of the adsorbate in the feed gas mixture fed to the bed during said mode, the concentration of the adsorbate in the feed gas mixture is monitored during said on-stream mode and the time required to complete the on-stream mode predicted from said monitored concentration, and at least one regeneration mode operating condition is modified in response to changes in said predicted time whereby the regeneration mode is completed at the same time as the concurrent on-stream mode.
