以３０％ＴＢＰ（煤油）为萃取剂，ＮａＯＨ水溶液为反萃剂，对聚砜中空纤维封闭液膜萃取苯酚的传质性能进行了实验研究，并在膜器的壳程鼓入空气以期强化过程传质性能研究结果表明，在中空封闭液膜萃取过程中总传质系数与料液相流速的１／３次方成正比因为反应速度很快反萃相的传质阻力可以忽略在鼓入空气的情况下，总传质系数较无气泡鼓入时明显增大总传质系数仍与料液相流速的１／３次方成正比，而与反萃相的流速基本无关气泡的鼓入不仅可使传质过程达到稳定的时间缩短，而且还可以在一定程度上强化传质过程
The mass transfer performance of phenols extracted with polysulfone hollow fiber membrane was investigated by using 30% TBP (kerosene) as extractant and NaOH aqueous solution as stripping agent, and air was blown into the shell of shell to enhance the process Mass transfer performance The results show that in the hollow closed liquid membrane extraction process, the total mass transfer coefficient is proportional to the third-order power of the liquid phase, because the mass transfer resistance of the stripping phase can be neglected When the air is blown into the air, the total mass transfer coefficient is obviously increased compared with that without bubbling. The total mass transfer coefficient is still proportional to the 1/3 of the liquid phase flow velocity, but has little relation with the flow velocity of the stripping phase. Bubble bubbling can not only shorten the mass transfer process to a stable time, but also can enhance the mass transfer process to a certain extent.
