| 摘 要： | 利用Aspen Plus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UNIQUAC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350kPa,塔板为30块,进料板为第10块塔板,回流比为1.5,在塔底可以得到质量分数为99.7%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. |
