ABSTRACT:
A charged adsorbent is accommodated in a desorbing vessel and in an intermediate container which communicates with the desorbing vessel. The charged adsorbent is desorbed in the desorbing vessel by contacting the same with a heat carrier, such as with hot sand, and a desorption gas which develops during the desorption of the charged adsorbent in the desorbing vessel is passed through the charged adsorbent accommodated in the intermediate container to capture at least one component of the desorption gas in the charged adsorbent present in the intermediate container. The purified desorption gas is withdrawn from the intermediate container, and the regenerated adsorbent is gradually discharged from the desorbing vessel and the supply of the adsorbent in the desorbing vessel is replenished by charged adsorbent from the intermediate container. The desorption gas is cooled during the passage thereof through the charged adsorbent present in the intermediate container. The magnitude of the temperature reduction of the desorption gas may be controlled by controlling the rate at which the desorption gas is discharged from the intermediate container, such as by resorting to the use of an adjustable vane. The adsorbent in the intermediate container may be confined by gas-permeable walls through which the desorption gas enters and leaves the adsorbent present in the intermediate container.
