摘要： In this work, mass transfer mechanism was studied for 50%TBP( in kerosene)-Phenol-Water as
the working system in different hydrophobic microporous hollow fiber modules. The effect of
different operating conditions on the removal of phenol was analyzed. Solvent entrainment
in this process was detected with MALVERN-2600 laser pellet diameter analyzed equipment.
Experimental results indicated the mass transfer coefficient increased as well as the two
phase flow rates are raised. With increases in the flow rate of the water phase, the
removal ratio of phenol will be decreased. Highly effective removal of phenol could be
reached by changing the experimental conditions and the module configuration. The solvent
entrainment in the water phase in the membrane extraction process was found to be 5-8% of
that in conventional liquid -liquid extraction process. Thus, solvent pollution could be
better controlled.
