A drop-population balance model is proposed for the prediction of the transient dispersed-phase fraction (holdup), drop size distribution, and solute concentration along a multistage mixer extraction column. Droplet events of breakage and coalescence and flow patterns inside the contactor are considered. The population balance model is suitable for model-based predictive control, and it is tested against experimental results of drop size distribution, holdup, and concentration profiles from a pilot plant unit. The dynamic behaviour and control of multistage extraction columns is also studied and a multivariable control scheme of holdup and concentration is proposed. (Authors)
