AZEOTROPIC DISTILLATION PROCESS

摘要

A PURGE STREAM DERIVED FROM AN AZEOTROPIC DISTILLATION COLUMN AND CONTAINING AN ENTRAINER, A HYDROCARBON, AND AN ALIPHATIC ACID (E.G. N -PROPYL ACETATE, A XYLENE AND ACETIC ACID RESPECTIVELY ) IS PROCESSED USING A STRIPPING COLUMN TO EFFECT SEPARATION OF THE ENTRAINER AND THE HYDROCARBON IN THE ORDER THAT THE ENTRAINER MAY BE RECYCLED TO THE AZEOTROPIC DISTILLATION COLUMN.(FIG.1)
