AZEOTROPIC MIXTURE SEPARATION METHOD, AZOTROPIC MIXTURE SEPARATOR AND DISTILLATION COLUMN

摘要

PROBLEM TO BE SOLVED: To separate a multicomponent mixture containing an azeotropic mixture into respective components to recover target matter at a low cost. SOLUTION: Azeotropic mixture vapor obtained by distillation in a distillation column is separated by a vapor permeable membrane and an absorption type freezer is operated by the heat possessed by a heating medium used in the condensation of one substance and a cooling medium generated herein is used in the condensation of other substance.
