摘要
Abstract
Two kinds of double-column distillation process, double effect heat integration distillation and separate heat pump distillation, for separation of methanol-dimethyl carbonate system were simulated based on the methanol-dimethyl carbonate system azeotropic character. The binary interaction parameters of Wilson equation were fitted against the reported experimental data of methanol-dimethyl carbonate system. Based on the minimum annual total cost, simulations for the two kinds of double-column distillation process were performed by Aspen Plus software to achieve the optimal condition. The simulation results showed that the two kinds of double-column distillation need lower energy consumption and less annual total fee. Compared with double effect heat integration distillation, separate heat pump distillation can save total capital fee by 2.69% and annual total fee by 17.33%.关键词
