| titleOfInvention | Method for separating acetone-isopropanol-water by three-tower heat integration extraction rectification |
| abstract | The invention relates to a method for separating acetone-isopropanol-water by three-tower heat integration extraction rectification. The device mainly includes: an acetone tower T1, an isopropanol tower T2, a solvent recovery tower T3, a heat exchanger H1 and a preheater H2. The invention adopts a three-tower rectification mode, firstly evaporates out acetone with lower boiling point, then separates the isopropanol-water binary azeotrope through extractive rectification to obtain high-purity acetone and isopropanol, adopts a two-stage condensation mode to cool the circulating extractant stream, realizes the high-efficiency utilization of the heat of the stream, and utilizes a heat integration mode to achieve the purpose of saving energy. The method solves the problems of complex process, high energy consumption and low product yield in the prior art, and improves the purity and the product yield of the product. |
