摘　　要：以丙二酸二甲酯、氢气为原料,通过等温反应后产物经分离及精制得到质量分数为99.9%的1,3-丙二醇产品。通过Aspen Plus软件对工艺流程及工艺操作条件进行了模拟和优化,从而实现了最优的操作条件。另外,通过采用热泵精馏、共沸减压隔壁精馏及换热网络优化等节能技术的优化设计,实现了流程共节约能耗30.2%,节能效果明显。此工艺流程的模拟设计为1,3-丙二醇的工业生产提供了一定的理论参考。Using dimethyl malonate and hydrogen as raw materials,1,3-propanediol product with a mass fraction of 99.9%was obtained through isothermal reaction and product separation and refining.The process flow and operating conditions were simulated and optimized using aspen plus software,resulting in optimal operating conditions.In addition,through the optimization design of energy-saving technologies such as heat pump distillation,azeotropic vacuum distillation,and heat exchange network optimization,a total energy saving of 30.2%was achieved in the process,and the energy-saving effect was significant.The simulation design of this process provides a theoretical reference for the industrial production of 1,3-propanediol.
