摘　　要：介绍了哌啶醇精制的工艺流程,运用Aspen Plus软件对精制过程进行了模拟,利用其中的组分自定义模块完成了哌啶醇和哌啶酮的物性估算,同时利用Aspen Plus的灵敏度分析工具对哌啶醇塔的理论塔板数及回流比(质量比)进行了具体的模拟优化。产品哌啶醇的质量分数达到99.66%,模拟结果与现场数据吻合较好,一方面验证了物性估算的准确性,另一方面也说明了采用的方法适用于哌啶醇精馏过程的模拟。The refining process of 2,2,6,6-tetramethyl-4-piperidinol was described, and the process was simulated with commercial software Aspen Plus. The component custom module was used to complete the property estimation. Moreover, through the sensitivity analysis of Aspen Plus, piperidinol tower was optimized under the condition of different theory stage numbers and different reflux ratios （mass ratios ）. The purity of the piperidinol was over 99.66% （mass fraction）. The simulation result agrees well with the actual measured data. The simulation method is available for this system and the property estimation is precise.
