Abstract
A thermal sink is used to recover heat from a product gas leaving an adsorption vessel in a thermal swing adsorption process. Heat that is recovered from the product gas is used to heat a regeneration gas during the subsequent regeneration of the adsorbent material within the adsorption vessel. The step in which the regenerated bed of adsorbent material is cooled prior to returning to adsorption mode is eliminated.
