ABSTRACT:
The apparatus includes an adsorber housing, beds of carbon mounted in the housing, the beds extending in generally vertical planes, and ducts for moving carbon downwardly through the beds from the upper side to the lower side of the housing. Air ducts are provided for conducting solvent-laden air into the housing and laterally through the beds, and conducting cleaned air out of the housing. A desorber for removing the solvent from the carbon includes a duct for conducting solvent-laden carbon received from the adsorber, an induction heater for heating the solvent in the carbon to vaporization temperature, and gas ducts for moving an inert gas through the carbon and thereby sweeping the solvent vapor from the carbon. The desorber includes a heater which may also be used for activation or reactivation of carbon.
