Abstract Study of the hydrodynamics of pulsed column is of vital importance in the scale up and understanding of such columns . The back mixing appears during the study of the hydrodynamic of the pulsed column , therefore the effect of the following variables on the back mixing , namely , frequency , amplitude , dispersed phase velocity and aqueous to organic phase flow rate ratio were studied . The central composite rotatable design was used in this study to conduct the effect of the studied variables . Accordingly , twenty - five experiments were needed with an extra 5 used for replication . Moreover Hooke & Jeeves pattern optimization method was adapted to determine the optimum conditions with respect to the studied variables . A column of 20 baffled 5 cm compartments was used , with an inside diameter of 5.08 cm . Gas- oil - water system was used under binary condition . The results shows that the optimum conditions at maximum back mixing are frequency ( 1.6 s ) , amplitude ( 4.5 cm ) , dispersed phase velocity ( 0.508 cm / s ) and aqueous to organic phase flow rate ratio ( 0.5 ) .
