HOLDUP OF O W EMULSION IN A PACKED-COLUMN FOR LIQUID MEMBRANE SEPARATION OF HYDROCARBON/

The dynamic holdup of O/W emulsion in a column packed with McMahon for hydrocarbon separation by a liquid membrane was correlated empiricall y. The emulsion flowed as a film on the packing surface, because the h ydrophilic packing was selected so as to be wetted with the emulsion a nd to reduce the membrane breakage. The emulsion flow was analogous tb liquid flow for a gas -liquid system with liquid - wettable packing, unlike dispersed-phase flow for an ordinary liquid-liquid system. The correlation roughly fitted previous results for liquid holdup in the g as - liquid systems.
