摘要:This paper proposes various side-stream extractive distillation configurations for the benzene/isopropanol/water separation with ethylene glycol as a solvent, including double side-stream extractive distillation (D-SSED), single side-stream extractive distillation (S-SSED) and conventional extractive distillation (CED). The parametric design is investigated with the minimum total annual cost (TAC) as an objective function. It is concluded that the D-SSED scheme is the best option, saving TAC by 31.52% and CO2 emission by 35.56% compared to the CED scheme. During this, one simulated annealing-based optimization procedure is firstly applied to such complex triple-column flowsheets. The accepted optimal solution is readily found through three rounds of search from one base-case. The procedure shows the advantages of time-saving, intelligence and global optimization compared to the common iterative sequential optimization method.
