    Abstract: 本文仿照熱交換器中熱傳送之修正因子分析,作平板萃取器中之質量傳送分析;兩相間之流動包括順流、逆流與交流。結果發現:順流與逆流操作之修正因子皆等於1,而交流操作者乃溶液濃度與分佈係數之函數,其關係以圖表示之。 The mass transfer for membrane extraction through a flat-plate module has been studied under concurrent-flow, countercurrent-flow and cross-flow operations. It was found that the mass transfer of solvent extraction in microporous-membrane mass exchangers can be analogous to heat transfer in heat exchangers, and also somewhat analogous to mass transfer of membrane dialysis except that in membrane extraction, both phases are immiscible. The correction factors for both concurrent-flow and countercurrent-flow operations were found to be the same and equal to unity. For cross-flow operation, the correction factor is a function of the fluid concentration and distribution coefficient, and is shown graphically.
