    Abstract: 本文以修正因子分析方法,推導出平板式薄膜萃取之質量傳送計算公式。結果發現,順流與逆流操作之修正因子皆為1,而交流操作時,修正因子為流率、質傳面積、分佈係數及總質傳係數之函數。本分析方法改良了傳統之分析法,理論計算時較為方便。
    The expressions of mass-transfer rate for membrane extraction through a rectangular module have been derived under cocurrent-flow, countercurrent-flow and cross-flow operation based on the modified correction-factor analysis. These expressions are explicit and the results can be readily calculated without using try-and-error method, which should be employed in the conventional correction-factor analysis for designing heat and mass 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, masstransfer area, distribution coefficient and overall mass-transfer coefficient, and some values of them are given graphically.
