The effect of a variable solute distribution coefficient on mass transfer in a hollow fiber separator is described. This problem occurs when liquid membranes are used in porous hollow fibers for mass separation. An example is the removal of toxic phenolic solutes from water. A variable solute distribution coefficient in the liquid membrane can have a significant effect on the separation performance of a hollow fiber module if the wall Sherwood number is less than 10. A distribution coefficient that increases with solute concentration gives increased mass transfer, and, therefore, better separation compared with a constant distribution coefficient. A distribution coefficient that decreases with solute concentration gives reduced separation in a hollow fiber module, particularly in the inlet region of the module. 17 refs.
