Abstract


Dispersed phase holdup is studied in a low plate free area pulsed sieve-plate extraction column. The effects of pulse velocity (product of amplitude and frequency) and superficial phase velocities are studied for two liquid-liquid systems with widely different interfacial tensions. Dispersed phase holdup is found to be affected strongly with the change in pulse velocity and dispersed phase velocity. The inclusion of solute increases the dispersed phase holdup.
