<p>PURPOSE: To sufficiently desorb a solvent from an adsorbent by preventing a foaming phenomenon,while keeping the adsorbing efficiency of the solvent high after desorption in a solvent recovering method. CONSTITUTION: In the solvent recovering method using an apparatus equipped with a solvent adsorbing column 1, the steam generator 5 provided to the lower part of the solvent adsorbing column, the condenser 10 provided to the solvent adsorbing column and the specific gravity separator 16 connected to the condeser 10 through first piping 14 and connected to the steam generator through second pipings 17, 19, 20 and supplying the water separated from a solvent by the specific gravity separator 16 to the steam generator 5 through the second pipings 17, 19, 21, a defoaming agent is added to the separated water.</p> |
