Patent ID: 7594956

Claim:
A temperature swing adsorption method for removing one or more strongly adsorbed components (SAC) from a process gas stream having SAC and other gaseous components in a sealed continuous flow sealed vessel, which comprises the steps of: (a) adjusting the temperature of a SAC-laden process gas stream to be between about 80° and about 500° C., (b) in said sealed vessel containing a plurality of horizontally disposed perforated trays through which perforations both gas and solids can pass simultaneously, taking the temperature-adjusted process gas stream and contacting with a heat-exchange surface to transfer heat to an adsorbent passing through said sealed vessel and countercurrently to said temperature-adjusted process gas stream, thus causing adsorbed SAC to be desorbed for collection, and to cool said process gas stream and removing any condensate from said cooled process gas stream; (c) contacting said cooled process gas stream with a cooled section of said adsorbent to adsorb SAC therefrom, producing a SAC-depleted process gas stream and a SAC-laden adsorbent; (d) withdrawing desorbed SAC from step (b) for collection; and (e) withdrawing any adsorbent fines for collection.
