<P>PROBLEM TO BE SOLVED: To provide an organic solvent recovery system including a configuration capable of reducing energy consumption in the organic solvent recovery system. <P>SOLUTION: In this organic solvent recovery system 1B, a part of clean gas (G3) derived from an adsorption part 22 is sent to a purge part 23, and purge part outlet gas (G6) is introduced into the adsorption part 22 together with organic solvent-containing gas (G2). An adsorption element at a desorption part 21 whose desorption is completed is shifted to the purge part 23, and cooled efficiently by the clean gas (G3) at the purge part 23. Adsorption performance at the adsorption part 22 is improved, and resultantly the energy consumption can be reduced as the whole system. <P>COPYRIGHT: (C)2012,JPO&INPIT |
