Provided are a solvent separation method, a solvent separation apparatus, and a solvent separation system that make it possible to easily collect a solvent removed from an exhaust atmosphere and that make it possible to easily carry out maintenance of exhaust gas pathways. An impeller (71) placed in a storage space (63) of a casing (62) is rotated to introduce a gas including a volatilized solvent (23) from an inlet (64) of the casing into the storage space, and the volatilized solvent is cooled and devolatilized by a collection face (83) that has been cooled so as to have a surface temperature lower than the temperature of the gas, thereby separating the solvent from the gas.
