Extractive distillation of acetone - methanol mixture with water as an extractive agent in partially thermally coupled columns

Abstract

Two different flow sheets of extractive distillation for separation of acetone - methanol various composition mixture with water as the extractive agent in the traditional two-column complex and in the partially thermally coupled columns is compared. It is shown, that the complex column provides economy of heat on 11.2-19.6%.
