Title:
METHOD AND APPARATUS FOR PURIFICATION OF DIMETHYL CARBONATE USING PERVAPORATION
Document Type and Number:
WIPO Patent Application WO/2016/105156
Kind Code:
A1
Abstract:
An apparatus for separating dimethyl carbonate using pervaporation includes: an atmospheric distillation column and a high pressure distillation column distilling a mixture containing dimethyl carbonate and methanol and separating dimethyl carbonate from the mixture; and a pervaporation membrane module disposed between the atmospheric distillation column and the high pressure distillation column and allowing for permeation of the methanol to separate the methanol from the mixture, thereby reducing heat consumption and a process cost as compared to the case of only using an existing pressure swing distillation method.
