• abstract = "For the separation of multi-component mixtures, compound distillation sequences (CDSs) comprising simple distillation columns (SDCs) and dividing-wall columns (DWCs) offer the advantage of significant energy-saving potential and relatively straightforward industrial implementation. This work proposes a design framework to facilitate the development of optimal CDSs. In this framework, genetic programming is employed to explore the optimal sequence; simultaneously, the exhaustive search method and the elitist genetic algorithm are separately employed to search for the optimal design of, respectively, SDCs and DWCs involved. Furthermore, to efficiently estimate the total annual cost (TAC) and both the flow rates and compositions of products of the SDCs and DWCs during the optimization process, artificial neural network (ANN)-based performance estimators were developed for them. An illustrative case study on n-butane/n-pentane/benzene/toluene/o-xylene/2,4-methyl-benzene mixtures is conducted. Analysis of the optimization results demonstrates a significant improvement in economic performance for the resulting CDS compared to the direct and indirect SDC sequences",
