萃取精馏法脱除焦化苯中微量甲基环己烷的工艺分析及模拟计算

SIMULATIVE CALCULATION FOR SEPARATING THE TRACE OF METHYLCYCLOHEXANE FROM COKING BENZENE BY EXTRACTIVE DISTILLATION

利用甲基环己烷－苯－ＤＭＦ的相平衡基础数据，采用Ｗａｎｇ－Ｈｅｎｋｅ的泡点法，进行精馏及萃取精馏的平衡级分离模拟计算，并提出净化苯的工艺流程。

The conventional and extractive distillation for separating the trace of methyl-cyclohexane from benzene based on the phase equilibirum relations was simulated by the Wang-Hanke BP method and a seperation scheme was pre sented.
