摘　　要：对某企业1,4-丁二醇(BDO)路线制备γ-丁内酯(GBL)的精制单元进行了流程模拟,模拟结果与企业运行数据极为接近。在验证模型合理性的基础上,对现有双塔工艺和隔壁塔(DWC)进行了模拟和系统优化。结果表明,DWC工艺具有最小的年总成本(TAC),比传统双塔工艺少1%,具有很好的发展前景。The process simulation of the refined unit for preparation of gamma-butyrolactone(GBL)from 1,4-butanediol(BDO)in an enterprise was carried out.The simulation results were very close to the enterprise operation data,which verified the rationality of the model.On this basis,the existing two-tower process,and dividing wall column(DWC)were simulated and optimized.The results showed that the total annual cost(TAC)of the DWC process was the lower than the two-column process.DWC process had a good development prospect.
