ABSTRACT:
Method and apparatus for in-situ regeneration of particulate adsorbent in a vessel including: heating the adsorbent, passing inert gas through heated absorbent to collect vaporized adsorbate, chilling the inert gas to condense adsorbate, thereafter lowering the pressure within the vessel, collecting withdrawn gases containing volatilized adsorbate, and chilling the withdrawn gases to condense adsorbate.
