压力变化对乙苯/苯乙烯塔分离效率的影响

Affection of Pressure Variation on Separation Efficiency of Ethyl-Benzene/Styrene Packed Tower

通过模拟计算,分析乙苯/苯乙烯塔压力变化对乙苯/苯乙烯、间二甲苯/苯乙烯、对二甲苯/苯乙烯相对挥发度的影响;压力变化对塔釜乙苯含量、间二甲苯含量、对二甲苯含量及塔顶乙苯中苯乙烯浓度的影响。得出降低操作压力,有利于提高粗苯乙烯塔分离效率的结论。

The present paper analyses the relative volatility of ethyl- benzene/styrene and meta- xylene/styrene and para - xylene/styrene is affected by pressure variation in ethyl- benzene/styrene packed tower, and also analyses the fi：actional composition is affected by pressure variation in above packed tower. According to the analysis, such concolusion that seperation efficiency is increasing with pressure dropping can be drawn m ethyl - benzene/styrene packed tower.
