摘　　要：利用Aspen Plus化工流程模拟软件对2种典型的乙酸乙烯精馏过程进行了模拟分析。分析了工艺1各操作参数对分离过程的影响,得到了较优进出料位置及所需的理论板数,讨论了造成某乙酸乙烯生产厂产品质量分数未达到分离要求可能的原因。在此基础上,采用相同的操作参数,对工艺2进行了分析,优化了进出料位置,并和工艺1做了产品质量分数和能耗之间的对比。结果表明,在相同的分离条件下,工艺2的产品纯度达到了分离要求,且冷凝器可节能22.5%,再沸器可节能37%,在产品质量分数和能耗方面均优于工艺1。Two typical vinyl acetate distillation processes are simulated and analyzed using Aspen Plus software.The influence of the parameters of process 1 on the separation process is analyzed. The optimal feed and discharge position and theoretical plates are obtained. The reason why the product quality of a vinyl acetate production plant does not meet the requirement of separation is also discussed. On this basis,the same operating parameters are used to analyze the process 2 and the positions of the feed and discharge are also optimized. The comparison between the product quality score and the energy consumption is performed. The results show that the purity of the process 2 reaches the separation requirement under the same separation conditions. Its condenser and reboiler can save energy up to 22. 5% and 37%,respectively,exhibiting better product quality and energy consumption than process 1.
