Summary: | Provided is a method of recovering a solvent, and more particularly, a method of recovering a solvent including: supplying polymerization reactants including one or more monomers and a solvent to a reactor to obtain a polymer solution (S10); supplying a stream including the polymer solution to a separator to separate an upper discharge stream including the solvent as a gas phase and a lower discharge stream including the polymer solution (S20); and heating a divergence stream diverging from a part of the lower discharge stream from the separator by a heating device and refluxing the stream to the separator, and supplying a residue stream including a residue of the lower discharge stream from the separator to a steam stripping process unit (S30), wherein a vapor mass fraction of the divergence stream which is refluxed to the separator after being heated by the heating device is adjusted by a pressure adjustment valve. |
