A direct synthesis approach to the PI tuning problem with application to a distillation column

The flooding behavior of a pilot plant Hanson mixer-settler extraction column has been investigated. This study presents flooding characteristicfor three different liquid-liquid systems with and without mass transfer conditions. A correlation proposed by Pratt was used successfully for theprediction of flooding characteristic. The validity of Pratt model was checked against the experimental flooding data in this column and fairly goodagreement is achieved.
