摘要
Abstract
Batch extractive distillation for isopropanol-water mixture was simulated and optimized. Simulation of batch extractive distillation was executed by BatchFrac module of Aspen Plus simulation software, based on UNIFAC model, glycol as the extractant. The effect on the process of different operation parameters was also studied, such as solvent ratio, mole reflux ratio, solvent feeding location, solvent feeding temperature. Sensitivity analysis was also performed to optimize the operation parameters. The simulation results showed that it was possible to separate isopropanol-water azeotropic mixture by batch extractive distillation using glycol as extractant. When isopropanol - water azeotropic mixture was l00kmol and stage numbers of extractive distillation column was 20, solvent feeding location was 3, solvent feeding temperature was 80℃, mole reflux ratio was 5 and solvent ratio was 2, the mass fraction of isopropanol at the column top could reach 0. 998. The results of simulation and optimization supply certain guidance for the deep application of batch extractive distillation in industry.关键词
