    Abstract: Solvent extraction through a countercurrently cross-flow multipass membrane module has been investigated both theoretically and experimentally. Considerable improvement of mass-transfer rate in a parallel-plate module of fixed dimensions is obtained if multipass, instead of single pass, are arranged in the phase (retentate phase or extract phase) where the mass transfer is dominated by its external film and not by the membrane resistance. Further, the performance in a countercurrently cross-flow device introduced in present study overcomes that in a cocurrently cross-flow one which we discussed in previous works.
    本文以理論與實驗方法,探討逆交流平板薄膜模組中多行程操作對萃取效率之影響,結果發現:若阻力非在薄膜內時,在流體相中設置多行程裝置,其效率遠比大小相同的單行程薄膜萃取器高,而逆交流操作又比順交流者為佳。
