<p><P>PROBLEM TO BE SOLVED: To efficiently recover a solvent from solvent-containing gas. <P>SOLUTION: The solvent recovering apparatus recovering solvent from the solvent-containing gas has a gas flow passage 1 provided with a pre-cooler 2, a water cooler 3 and a condenser 4 for condensing the solvent-containing gas in this order. A coolant is supplied to the condenser 4 from a direct expanding type freezer system, so that the temperature of the condenser becomes 4 to 2°C. Thus, the solvent is efficiently recovered while preventing freezing of water contained in the gas. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
