使用Aspen Plus软件，对隔板塔体系进行了设计优化，开发并验证了一种隔板塔稳态优化的良好策略。通过灵敏度分析等手段分析了各个变量因素的影响，发现固定分气比分液比，四个塔段塔板数有多种分配方案，调整左右两侧塔段塔板数及进料采出位置比例时，公共精馏段和公共提馏段最优塔板数基本不变且最优分气比分液比在一定范围内波动；固定公共精馏段和公共提馏段塔板数，N×（R+1）随着N先减小后增大，存在着最优的选择方案。

The design of dividing wall column system is optimized by using Aspen Plus software,and a good strategy for steady-state simulation optimization of dividing wall column is developed and verified.The interconnections of various variables are analyzed by means of sensitivity analysis and the results are as follows:there are many distribution schemes of the number of trays in the four column sections when both liquid and vapor split ratios are fixed;The sensitivity analysis shows that the optimal number of trays in the common rectification section and the common stripping section remains unchanged when adjusting the number of trays on the left and right sections of the dividing wall column,and the locations of the feed stream and side product stream.The liquid and vapor split ratios vary within a certain range.N×(R+1) increases as N decreases first and increases then when fixing the number of trays in the common rectification section and the common stripping section,the best selection scheme is existed.
