“…However, the DSE calculation results of the columns with different numbers of walls and different positions of walls are the same; this cannot reflect the influence of the number of walls in the column and the position of walls on the evaluation index of the distillation sequence. Bonet's research shows that DSE cannot reflect the effects of the direct thermal coupling stream on the energy consumption of the distillation 36 . Considering these problems in DES, η was deduced based on DSE and used as the index of evaluation and screening in this paper.…”

“…In addition, the evaluation index of the distillation sequence is the fundamental factor for evaluating the accuracy of the model. Pleşu et al 36 proposed the Distillation Sequence Efficiency (DSE) for the selection of distillation sequences. The advantage of DSE is that it only needs the two parameters of the feed composition and product boiling points to select the distillation sequence.…”

BACKGROUND: Distillation is a separation process with a high energy consumption. Therefore, energy-saving optimizations of the distillation process have become particularly significant. However, developing methods to quickly choose the best energysaving distillation sequence for the separation of multiple components has become a key problem. RESULTS: In this paper, the Distillation Sequence Morphometry Analysis Method (DSMAM) was established to quickly screen energy-saving and efficient distillation sequences and was integrated with a Dividing-wall column (DWC) device, which has more industrial significance. Meanwhile, an evaluation and screening index η of separated multicomponent energy-saving distillation sequences was proposed. Finally, based on the DSMAM, and combined with Microsoft Visual Basic 6.0 (VB) and Aspen Plus V11 (Aspen) software, a set of distillation sequence screening and evaluation programs of four-component separation systems was generated. The distillation column sequence with high thermodynamic efficiency and the energy-saving coupling structure of distillation were obtained quickly and accurately. CONCLUSION: This program was applied to the separation of the n-butane-benzene-n-heptane-n-nonane system. It was able to quickly obtain the first three energy-saving distillation sequences without thermal coupling and the first three energy-saving distillation sequences in the search space. The direct-thermal coupling distillation sequence of the energy-saving fluid was integrated and coupled, providing a preliminary design reference for industrial design and application.
