The overall extraction coefficient Ka was calculated on the basis of the phase P which offered the major resistance to solute transfer compared to the water phase W. Taking for instance the system benzene-acetone-water the log mean driving force was based on CB I and CO and on the equilibrium concentration in the benzene phase corresponding to the observed concentration in the water phase. [...] The rate of extraction could be calculated from the rate of flow of the solvent and solution and from the change in the concentration of water or of the solvent phase. [...] Elgin and Browning5 and Appel and Elgin2 found in the case of spray and packed columns that with the increase in the flow rate of the dispersed phase there was an increase in the hold-up but with increase in the continuous phase flow rate the hold-up values remained more or less constant. [...] The relationship as found above between the flow rate of the dispersed and continuous phase with the extraction coefficient was not corroborated by Johnson and Bliss" Bergelin et al.3 and Comings and Briggs4 who came to the conclusion that the flow rate of the dispersed phase had considerable effect on the coefficient but that of the continuous phase also had a smaller effect on the coefficien [...] The increase in the values of the extraction coefficient with increase in the flow rate of the dispersed phase is due to a greater agitation and also due to an increase in the number of drops and hence in the specific contact area 'a'.
