A novel reciprocating‐plate liquid‐liquid extraction column is proposed. It features a simple design that utilizes as the plates mesh screens with a fractional free area larger than 64%. A hydrodynamic and mass transfer study of the column was carried out in which the existence of a uniform liquid‐liquid dispersion throughout the column at relatively low speeds of plate reciprocation was confirmed. Experimental results show that in comparison with other reciprocating columns, the present column has these desirable qualities: (1) large dispersed phase holdup and overall mass transfer coefficient, (2) low power requirements, (3) high flow capacity. A correlation of the dispersed phase holdup data based on slip and drop characteristic velocities is presented. The drop characteristic velocity for the screen plate column is empirically related to the power dissipation rate and system properties. On propose une nouvelle colonne d'extraction liquide‐liquide munie de plateaux réciproques. Il s'agit d'une conception simple qui utilise comme plateaux des tamis à mailles avec une zone libre fractionnelle supérieure à 64%.
