Performance Map for the Design of Liquid-Liquid Extraction Columns

For the fast approximation of liquid-liquid extraction column designs via HETS (height equivalent of a theoretical stage) values and flooding points, a population balance model was developed. The model requires only one pilot-scale column experiment to fit a coalescence parameter. The comparison of experimental data with simulations shows good agreement for a stirred extraction column. With the model, the operation domain of the column is simulated and visualized in a performance map, showing the holdup, the distance to the flooding point and HETS values.
