本文主要探討在三行程交流式薄膜萃取系統中質量傳送速率之改良型修正因子分析。本研究對三行程交流式薄膜萃取系統的質傳面積、體積流率、分配係數和整體質量傳送係數等參數，繪製出的改良型修正因子圖表，無須經過繁雜的疊代步驟，即可直接由圖表得到修正因子，並配合本文中改良後的質傳速率公式，就能容易的求解出薄膜萃取速率，比起傳統的修正因子分析圖表，因含有未知出口濃度的因素，而在計算上必須使用繁雜的疊代法，改良型修正因子分析則改善了求解萃取速率的便利性。此改良型修正因子分析的概念也可應用於其他傳統的熱、質傳交換器中，本研究採以甲基異丁基酮(MIBK)薄膜萃取醋酸實驗結果來對改良型修正因子分析所得到的萃取速率理論值進行佐證。

The expressions of mass-transfer rate for membrane extraction through a cross-flow multipass membrane module have been derived based on the modified correction-factor analysis. These expressions, as well as the correction-factor charts modified, 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. Experimental results confirm the predicted values for membrane extraction of acetic acid from aqueous solution by methyl isobutyl ketone in cross-flow multipass device.
