摘要: 利用 A s p e nP l u s化工模拟流程软件对乙腈 - 水共沸体系进行变压精馏模拟分离研究。选择 UN I QUAC物性计算模型确定变压精馏的工艺流程, 通过灵敏度分析模块分别考察高压塔和常压塔的进料板位置 和回流比对分离效果的影响。模拟结果表明, 当塔操作压力为3 5 0k P a, 塔板为3 0块, 进料板为第1 0块塔板, 回流比 为1. 5, 在塔底可以得到质量分数为9 9. 7%的产品乙腈。

Abstract: A process of pressureswing distillation for separation of acetonitrileand water was simulated by using Aspen Plus. The UNIQUAC equation was used for calculating vaporliquid equilibrium data of acetonitrilewater mixture. The relationship between the feed stage and reflux ration for the separation of acetonitrilewater was studied by sensitive analysis. The requirement for acetonitrile reached to 99.7%, when the high column at the pressure was 350 kPa, the number of stages was 30, the feed stage was 10 and the mole reflux ration was 1.5.
