Abstract: Apparatus for use in a dry cleaning plant having dry cleaning machines using a liquid solvent comprises a plurality of filter cartridge housings, an adsorber containing a bed of activated carbon pellets, a condenser and a solvent-water separator all mounted on a still housing. Valve-controlled conduits are provided for selectively circulating solvent through filter cartridge in said cartridge housings, draining the filter cartridges, connecting cartridge housings to the adsorber to desorb filter cartridges, supplying steam to cartridge housing to strip filter cartridges of solvent, passing air containing solvent vapor through the adsorber to remove the solvent vapor from the air, supplying steam to the adsorber to desorb the carbon bed and supplying steam to a heating coil in the still to distill solvent.
