| 摘 要： | 提出了一种应用反应精馏隔壁塔合成乙酸甲酯的新工艺流程,采用反应精馏隔壁塔替代常规反应精馏流程中的反应精馏塔及甲醇回收塔。利用Aspen Plus模拟软件,对反应精馏隔壁塔及常规流程进行了模拟,比较分析了两种流程塔内液相组成分布,并分析了塔顶回流比与气相分配比对反应精馏隔壁塔的影响。结果显示新流程可以节能11.9%,并能降低设备投资费用和操作费用。

| Abstract: | A novel single-column reactive distillation process was proposed for synthesis of methyl acetate,in which the reactive distillation dividing wall column was used instead of conventional reactive distillation column and methanol recovery column.Both the new process and conventional process were simulated with Aspen Plus.Liquid composition profiles of the two processes were compared.The influence of important parameters,such as the reflux ratio and vapor distribution ratio,on the performance of the novel proc... |
