PROBLEM TO BE SOLVED: To provide a system for treating a gas containing an organic solvent, with which the running cost can be suppressed while improvement in the purification capacity of a raw gas and the recovery rate of the organic solvent are targeted.SOLUTION: The system 1A for treating a gas containing an organic solvent includes: a circulation path for flowing a carrier gas; and a first adsorption and desorption device 100; a second adsorption and desorption device 200; and a condensation and recovery device 300, all being disposed on the circulation path. The first adsorption and desorption device 100 includes first adsorption and desorption elements 121, 131. The second adsorption and desorption device 200 includes a second adsorption element 210. The second adsorption and desorption device 200 includes: a first treatment part 220 disposed on the circulation path in the downstream side of the first adsorption and desorption device 100; and a second treatment part 230 disposed on the circulation path in the downstream side of the condensation and recovery device. The second adsorption element 210 is configured to have its arbitrary part move between the first treatment part 220 and the second treatment part 230 heading toward alternately with time. |
