设计分隔壁塔（DWC）-三元混合物的节能分离器-涉及多变量问题的解决。这些变量相互影响，需要同时优化以获得最佳设计。在这项工作中，一个实用的方法，采用响应面法（RSM）提出的DWC的设计和优化。最佳DWC结构可以找到一个实用的方式，同时最大限度地减少模拟运行。该方法在醋酸精制过程的设计和优化中得到了验证。基于响应面的优化有效地处理了优化变量之间的相互作用，其预测结果与严格的模拟结果吻合良好。与常规蒸馏相比，采用该方法设计的DWC系统年总费用降低了44.57%。
Designing dividing wall columns (DWC) – energy-efficient separators of ternary mixtures – involves multivariable problem solving. These variables interact with each other and need to be optimized simultaneously to obtain the best design. In this work, a practical method employing response surface methodology (RSM) is proposed for DWC design and optimization. The optimum DWC structure can be found in a practical manner while minimizing simulation runs. The proposed method was tested in the design and optimization of an acetic acid purification process. The RSM based optimization effectively copes with interactions between optimizing variables and its predictions agreed well with the results of rigorous simulation. The DWC system designed by the proposed method decreased total annual costs by 44.57% compared with conventional distillation.
