DEVICE AND METHOD FOR RECOVERING 1,2-DICHLOROETHANE

摘要

PURPOSE: A device for recovering 1,2-dichloroethane is provided to drastically reduce steam consumption and to maximize the efficiency of a distillation tower by simultaneously removing a light fraction and a heavy fraction in a primary distillation tower. CONSTITUTION: A device for recovering 1,2-dichloroethane comprises: a feed part(2a) to which only mixture including undissolved 1,2-dichloroethane(2) and impurities excluding a mixture including 1,2-dichloroethane and impurities generated from an oxychlorination reactor; a light fraction removal part(3a) removing impurities with low boiling point compared with 1,2-dichloroethane; a heavy fraction removal part(9a) removing impurities with high boiling point compared with 1,2-dichloroethane; and a recovery part(8a) collecting the purified 1,2-dichloroethane to the side of the distillation tower.
