Abstract
Published experimental results for the dispersed phase hold-up in pulsed perforated-plate extraction columns are considered. Based on 1574 data points in the absence of solute transfer for 14 liquid-liquid systems a single empirical correlation is developed which predicts the hold-up in the mixer-settler, transition and emulsion regions of operation to within 17% from the physical properties and operating variables. The same correlation with modified constants (but unchanged indices) can be used when solute transfer occurs in either direction. Futhermore, this correlation also predicts the boundary between mixer-settler and transition regions of operation.
