SEPARATION OF AZEOTROPIC MIXTURES BY BATCH DISTILLATION USING AN ENTRAINER

Batch Distillation is an efficient unit operation which allows the sep aration of a multicomponent mixture into its components in a single co lumn. However, the separation of azeotropic mixtures via distillation is quite complex because at the azeotrope liquid and gas have the same composition and, therefore, the driving force for distillation disapp ears. A systematical presentation of batch distillation processes for separating binary azeotropic mixtures using an entrainer is given.
