摘要

Mass transfer of solvent extraction in microporous-membrane mass exchangers can be analogous to heat transfer in heat exchangers. The correction factors for both cocurrent-flow and countercurrent-flow operations may be taken as unity when the logarithmic-mean concentration differences are properly selected. For cross-flow operation, the correction factors are function of flow rate, mass-transfer area, distribution coefficient and overall mass-transfer coefficient, and some values of them are given graphically.
