摘要:
以乙二醇为溶剂,使用Aspen Plus化工模拟软件中的BatchFrac模块,基于UNIFAC模型,对异丙醇-水二元共沸物的间歇萃取精馏过程进行间歇萃取精馏模拟,研究了不同操作参数(如溶剂比、回流比、溶剂进料位置、溶剂进料温度等)对整个精馏过程的影响,对各工艺参数进行了分析与优化。结果表明,对于处理量为100 kmol的异丙醇-水溶液,精馏塔具有20块塔板,溶剂比为2,回流比为5,溶剂进料位置在第3块塔板,溶剂进料温度为80 ℃时,塔顶异丙醇质量分数可达0.998,收率可达0.978。
Abstract:
Batch extractive distillation for isopropanol-water mixture was simulated and optimized. Simulation of batch extractive distillation wasexecuted by BatchFrac module of Aspen Plus simulation software, based on UNIFACmodel, glycol as the extractant. The effect on the process of different operation parameters was also studied, such as solvent ratio, mole reflux ratio,solventfeeding location, solvent feeding temperature. Sensitivity analysis wasalso 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 100 kmol 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 atthe 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.
