摘　　要：采用Aspen Plus软件,对MTBE(甲基叔丁基醚)装置进行了全流程模拟,模拟结果与实际值吻合良好。在此基础上,考察了工艺参数对催化精馏塔、萃取塔和甲醇回收塔影响,得到了优化的工艺参数:醇烯比为1.5,催化精馏塔回流比为1.05,萃取塔溶剂比为0.21,甲醇回收塔塔顶采出率为0.107,甲醇回收塔回流比为5。通过工艺参数优化,MTBE产品质量分数达98.8%,MTBE回收率达99.71%,异丁烯转化率达98.52%,催化精馏塔和甲醇回收塔的总热负荷可降低7.4%。Process simulation of methyl ten-butyl ether （MTBE） unit is carried out by using Aspen Plus simulation software. The simulation results agree well with the actual value. The effect of process parameters on catalytic distillation column, extraction column and methanol recovery column is investigated. The optimized process parameters are obtained as follows：l. 5 of ratio of methanol to isobutene, 1.05 of reflux ratio of catalytic distillation column,0. 21 of solvent ratio of extraction column,O. 107 of overhead recovery ratio of methanol recovery column and 5 of reflux ratio of methanol recovery column. Under the optimized condition, the mass fraction and the recovery ratio of MTBE can reach 98. 8% and 99.71% , respectively. Isobutene conversion can reach 98.52%. The total heat duty of catalytic distillation column and methanol recovery column is reduced by 7. 4%.
