Abstract
The present invention generally relates to a method to enhance heat transfer in the temperature swing adsorption process (TSA) and to an intensified TSA process for gas/liquid purification or bulk separation. Helium is designed as the heat carrier media to directly bring heat/cool to the adsorbent bed during the TSA cycling process. With helium's superior heat conductivity, the time consuming regeneration steps (warming, regeneration and precooling) of TSA process can be significantly reduced and allowing for the TSA process to be intensified.
