The volumetric overall mass transfer coefficients of a pulsed perforated plate extraction column have been measured using two different liquid–liquid systems. The effects of operational variables such as pulsation intensity and dispersed and continuous phases flow rates on volumetric overall mass transfer coefficients have been investigated and found to be significant. The variations of volumetric overall mass transfer coefficients along the column have also been investigated. In the present work, the dispersed phase overall mass transfer coefficient was predicted by using the twofilm model, i.e., the addition of two individual resistances of the dispersed and continuous phases. Dispersed phase mass transfer coefficient was calculated from Handlos and Baron equation and by using which an empirical correlation was proposed for prediction of continuous phase mass transfer coefficient. The prediction of overall mass transfer coefficients from the presented model is in good agreement with experimental results.<\div>
