ABSTRACT:
A process for recovery of halocarbons from a gas mixture containing the halocarbon and acid gas components comprises the steps of contacting the gas mixture with a dry scrubber to remove the acid gas components from the gas mixture and yield a first effluent gas mixture containing the halocarbon. The first effluent gas mixture is contacted with an adsorbent which is selective for the halocarbon component of the first effluent gas mixture to adsorb the halocarbon component and yield a second effluent gas. The adsorbed halocarbon is recovered by desorbing same from the adsorbent. The process of contacting with adsorbent can be carried out in at least two adsorbent beds joined at inlet and outlet ends thereof to gas feed and gas discharge manifolds, respectively.
