Abstract :
Sauter mean drop sizes have been measured in a pulsed packed extraction column for
two liquid systems with and without mass transfer conditions. The effects of pulsation
intensity, phase flow rates, and interfacial tension on drop size have been investigated
under a variety of operating conditions. The drop size is influenced mainly by pulsation
intensity and interfacial tension. Significant, but weaker, are the effects of continuous
and dispersed phase flow rates. A precise correlation is proposed for predicting mean
drop size in terms of operating variables, physical properties of the liquid systems and
mass transfer direction. Good agreement between prediction and experiments is found
for all operating conditions that were investigated.
