Method of and apparatus for the mass transfer between three liquid phases wherein two phases are miscible and the other one of said phases is immiscible with the other two phases and serves as an intermediate phase. The method comprises flowing the two miscible liquids in a capillary-gravitational mode down surfaces which are wettable by said immiscible liquid, said surfaces being separated by a space occupied by the third, intermediate phase, said third phase being forcibly circulated in a direction which is countercurrent with respect to the other two phases. The apparatus comprises a housing containing a package of alternating film carriers and distributors for the treated phase and the receiving phase, respectively, and discharge collectors for the treated phase and the receiving phase, respectively, said distributors being located at the top end and said collectors being located at the bottom end of the housing, respectively.
