目前，还没有研究集中在提高经济效率和环境可持续性的经典萃取精馏（CED）过程中，通过使用蒸汽再压缩热泵（VRHP）和中沸精馏塔。为了提高直接CED（DCED）和间接CED（IECD）分离丙酮/正庚烷共沸物的经济性和环境可持续性，引入了VRHP结构和中沸物苯。采用序贯迭代法对DCED和ICED进行优化，以年总费用（TAC）最小为目标。此外，六个独立的VRHP-DCED和六个独立的VRHP-ICED序列的设计和优化，以尽量减少蒸汽和电力消耗。结果表明，ICED工艺优于DCED工艺，部分VRHP-CED工艺在经济性、节能性和环保性方面优于ICED工艺。与ICED相比，VRHP-DCED（V）序列的蒸汽消耗量最小，比ICED序列减少83.38%，而VRHP-ICED（IV′）序列的总可吸入空气总量和烟气排放量最小，比ICED序列分别减少8.24%和26.87%。
Currently, no research has focused on improving the economic efficiency and environmental sustainability of the classic extractive distillation (CED) process through using both vapor recompression heat pump (VRHP) and intermediate-boiling entrainer. In this paper, both VRHP configuration and intermediate-boiling entrainer benzene are introduced to improve economic efficiency and environmental sustainability of the direct CED (DCED) and indirect CED (IECD) sequences for separating the acetone/n-heptane azeotrope. The DCED and ICED are optimized by sequential iterative procedure, aiming at the minimum total annual costs (TAC). Furthermore, six independent VRHP-DCED and six independent VRHP-ICED sequences are designed and optimized to minimize steam and electricity consumption. The results illustrate that the ICED sequence can outperform the DCED sequence, while a part of the VRHP-CED sequences demonstrate the advantages compared to the ICED sequence in terms of economic, energy and environmental performance. The comparison with the ICED sequence shows that the VRHP-DCED (V) sequences with the minimum steam consumption can cause a decrease by 83.38%, while the VRHP-ICED (IV′) sequences with the minimum TAC and gas emissions can cause a reduction by 8.24% and 26.87% compared with the ICED sequence, respectively.
