| 摘 要： | 多升液管筛板搭（MU）是芳烃抽提装置的一种新型萃取塔。在直径为0．1m、萃取段高度为1m的MU萃取塔中，用低界面张力体系正丁醇-丁二酸-水研究了分散相存留分数、液滴平均直径和液泛速度等流体力学特性以及全塔效率等传质性能。由试验数据回归得到的液泛速度、塔板效率等经验关联式可用于对该塔型的工程放大设计中。

| Abstract: | The multiple upcomer (MU) extraction tray was specifically developed for aromaticsextraction. Hydrodynamic and mass transfer experiments were carried out with n-butanol-succinic acidwater as an experimental system in a MU tray extraction column with a diameter of 0.1m. The dispersedphase holdup, drop size and the overall efficiency were measured and the hydrodynamic and mass transferparameters were correlated. The flooding velocities and the overall efficiency predicted from the correlationequations were in conformity with the experimental data. |
