The present invention relates to a distillation device. The distillation device of the present invention can minimize loss of energy generated in the process of purifying raw materials comprising an olefin monomer and a solvent, for example, 1-octene, iso-octene, and n-hexane, which are used in the process of polymerizing a polyolefin elastomer. Also, by separating a product with high purity, the distillation device can have improved cost-efficiency of the process. The distillation device comprises: a first distillation unit including a first condenser, a first reboiler, and a first distillation column; a second distillation unit including a second condenser, a second reboiler, and a second distillation column; and a heat exchanger. |
