摘要

采用模拟软件Aspen Plus,以离子液体[HMIM][NTf_2]为萃取剂,对甲醇-甲乙酮共沸物的萃取精馏进行了模拟优化。确定了离子液体作为甲醇-甲乙酮萃取精馏萃取剂的可行性,分析考察了萃取精馏塔的塔板数、萃取剂流量、闪蒸罐压力等因素对年总费用TAC的影响,并对流程进行了热集成分析,结果表明,与常规萃取精馏相比,热集成流程的TAC下降了18.7%。
        Aspen Plus was used to simulate and optimize the process of extractive distillation for methanol and methyl ethyl ketone system with ion liquid [HMIM][NTf_2] as the solvent.The feasibility of the extractive distillation process with [HMIM][NTf_2] as solvent was analyzed using the residual curve.To find the optimal design of the extractive distillation systems,total annual cost(TAC) was used as the objective function to be minimized.In addition,heat integration technology was used to reduce the TAC.The results showed that the TAC was reduced by 18.7% after using heat integration technology.
