摘　　要：采用AspenPlus软件对甲醇双塔精馏过程进行模拟与分析,分别研究了回流比、萃取水量、馏出比对精馏塔分离效果的影响,确定了最优工艺参数,甲醇的质量分数为99.9%,萃取水用量为770kg/h。Aspen Plus software was used to simulate and analyze the distillation process of methanol in twin columns. The influences of reflux ratio,extraction water amount and distillation ratio on the separation effect of distillation column were studied respectively,and determined the optimal process parameters. The mass fraction of methanol was 99.9%,and the amount of extraction water was 770kg/h.
