摘　　要：对四塔甲醇精馏节能流程提出了四项优化措施,利用PRO/Ⅱ工艺模拟软件,进行了工况研究。结果表明,采用优化后的工艺流程,甲醇回收率可提高约0.3%,预精馏塔能耗降低约7%;并根据工况研究结果和生产数据,提出了各塔合适的理论级数和操作参数,推荐了各塔结构形式、参考塔径、填料高度或塔盘层数。Four energy-saving optimization recommendations were made for the methanol distillation process of four columns. The distillation process was simulated with PRO/Ⅱ,and the result showed that methanol recovery rate was improved by 0.3% and the energy consumption of the pre-distillation column was lowered by 7% after adopting the optimized process. Based on the simulation study and actual production data,the appropriate theoretical stages and operation parameters of each column were determined,and columnstruct...
