摘要
以乙醇-异丙醇体系为研究对象,分别采用常规精馏、双效精馏、双效热泵精馏进行分离,使用Aspen Plus流程模拟软件进行模拟计算,以年总费用最低为目标函数,得到了相关的工艺参数,结果表明,双效热泵精馏的年综合费用比双效精馏节约了59.5%,比常规精馏节约了77.5%。
Three distillation techniques, including conventional distillation, double-effect distillation, and double- effect heat-pump distillation, were employed to separate ethanol-isopropanol mixture. The processes were calculated and simulated by Aspen Plus. The processes were optimized with process scheme and operating conditions with the goal of the minimum annual total cost. The results showed that the double-effect heat-pump distillation saves up to 59. 5% of annual total cost compared with double-effect distillation and to 77.5% compared with conventional distillation.
