| 摘要 |
The present application relates to a distillation apparatus and a distillation method. The distillation apparatus of the present application can minimize energy loss occurring in a process of purifying a raw material including a monomer and a solvent which are used in a polymerization process of a thermoplastic elastomer, can reduce the installation cost of the distillation apparatus as compared to when two distillation columns are used for the purification, and can thus improve the economic efficiency of the process. |
