以年总操作费用(TAC)和再沸器负荷为目标，提出了基于遗传算法 NSGA-Ⅱ的优化方法，并将该方法应用于BTX分离隔壁塔的优化设计。首先应用Aspen Plus软件建立了BTX分离工艺的隔壁塔Radfrac两塔模型，并在Matlab平台上，通过MAP接口工具箱实现Matlab对Aspen Plus的操作与控制，同时Matlab调用NSGA-Ⅱ进行优化，完成种群大小为600、遗传代数为28的模拟过程，得到了10组Pareto解。研究表明，对于Pareto解分布，气相分配量βg、液相分配量βL、侧线抽出位置NS和液相分配位置NL基本不变，进料位置NF、预分馏塔板Nj和主塔板数Ni存在一定的线性关系。

An optimized method was used to evaluate the performance of dividing wall columns in BTX separation with multi-objective genetic algorithm to minimize theTAC andHeat duty. A two-column Radfrac model was established for the separation of BTX by Aspen Plus software. Matlab can operate and control Aspen Plus using MAP and it can use NSGA-II for optimization. Ten Pareto fronts were obtained with population of six hundred and generation of twenty-eight. The results show that interconnection vapor flowβg , interconnection liquid flowβL, stage of side productNS and stage of interconnection liquidNL are relatively stable on the base of distribution of Pareto front. However, there is a linear relationship between the number of the stages of prefractionator and that of the main column. The feed stage has a linear relationship with the prefractionator stage numbers.
