PROCESS FOR CONDENSING ADSORBABLE AND DESORBABLE GASES AND DEVICE FOR IMPLEMENTING IT

摘要

The present invention refers to a procedure for condensing adsorbable and desorbable gases which are adsorbed on solid adsorption agents from a gas mixture with a relatively low concentration of adsorbable and desorbable gases; in which the gas released during desorption is condensed by cooling in a cooling stage; in which a gas mixture with a relatively high concentration of adsorbable and desorbable gases is fed directly into a cooling stage thus condensing most of the adsorbable and desorbable gas and in which the non-condensed gas mixture is returned to theadsorption. Furthermore a gas mixture of any concentration of adsorbable and desorbable gases can be fed to an adsorption /desorption stage with desorbed gas being returned via a heater in the desorption stage to the adsorption/desorption stage and a part of the desorbed gas being fed to at least one cooling stage for condensing the desorbedgas.
