摘　　要：本文针对热耦合精馏过程中的多稳态现象进行分析研究,通过隔板塔四塔等效模型,研究其多解现象。借助Aspen plus流程模拟软件灵敏度分析工具及等高线图,分析回流比对隔板塔内出现的多稳态解数目的影响。结果表明,随着回流比数值的变化,隔板塔内多稳态解数目也随之变化。In this article,four-column model was set up and used to analysis these multiple steady state solutions phenomenon occurring in the dividing wall column distillation. Besides,with the help of sensitive block of Aspen Plus simulation software and contour graph was employed to analyze the effects of reflux ratio on the number of steady states occurring in the dividing wall column. The results show that the number of steady states solutions occurring in the dividing wall column will vary with the values of reflux ratio.
