ABSTRACT:
A solvent adsorber includes a plural number of adsorbent material units of molded honeycomb structure with sheet heaters interposed between the respective units. The sheet heaters generate heat upon current supply to heat up the adsorbent material. As a result, the adsorbent material releases the adsorbed solvent therefrom. A solvent recovery system is used to pass solvent-containing gas through the solvent adsorber in a first main adsorption tower to obtain a clean gas which has been stripped of the solvent by adsorption on the adsorber. In a second main adsorption tower with a similar adsorber, current is supplied to the sheet heaters to release the solvent from the adsorber and at the same time the tower is evacuated to draw out a concentrated solvent gas. The concentrated solvent gas from the second main adsorption tower is sent to a condenser to condense and collect the solvent in liquefied form. In this system, the adsorber in each adsorption tower is regenerated in dry state, obviating the use of steam.
