摘　　要：借助Aspen模拟软件平台,对以环己酮、过氧化氢为原料,B2O3/γ-Al2O3固体酸两步催化合成ε-己内酯的产物体系的精馏分离工艺进行了模拟计算。在考虑各组分特性的基础上,采用UNIQ-NTH物性方法、RadFrac严格模型,分别对精馏塔的串联流程及并联流程进行了模拟计算。结果表明:并联流程优于串联流程,模拟计算结果能够满足工艺及产品的分离精度要求。通过对并联流程各精馏塔进行详细的模拟计算,得到了可为实际分离工艺设计和生产操作过程提供依据的数据。Using the platform of Aspen Plus engineering software,the distillation process for the ε-caprolactone product mixture from two-step catalytic reaction of cyclohexanone and hydrogen peroxide with B2O3/γ-Al2O3 catalyst was simulated.Based on the consideration of the product properties,used the UNIQ-NTH method and the RadFrac module to carry out the calculation of the series connection distillation process and the parallel connection distillation process respectively.The results showed that the parallel connection distillation process was superior to the series connection distillation process,the process was reasonable and it could meet the requirement of products separation.Then every rectifying column in the parallel connection distillation process was simulated in detail and the reliable data which will provide help for the process design and practical operation was gained.
