Method of recovering solvent and solvent recovery apparatus |
| abstract |
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; supplying a stream including the polymer solution to a separator to separate an upper discharge stream including the solvent, wherein the solvent is in a gaseous phase, and a lower discharge stream including the polymer solution; heating a divergence stream including a part of the lower discharge stream from the separator by a heating device and refluxing the divergence stream to the separator; supplying a residue stream including a remainder of the lower discharge stream from the separator to a steam stripping process unit; and adjusting a vapor mass fraction of the divergence stream which is refluxed to the separator with a pressure adjustment valve after being heated by the heating device. |
