Transfer of hydrocarbons in an O/W emulsion drop was simulated by the dimensionless multi-layer liquid membrane model in order to find a way of improving the separation selectivity of an emulsion liquid membrane, which will be of practical use. The results suggested that the selectivity of the emulsion membrane, lowered by the unfavorable concentration profile which appeared in an emulsion drop, would be improved by decreasing the number of inner oil droplets in the emulsion drop.<BR>A series of batch permeation experiments were conducted with a one-dimensional supported liquid membrane and an emulsion liquid membrane. The separation selectivity of the supported membrane was equivalent to that of the mono-layer liquid membrane and that of the emulsion membrane was lower. Selectivity of the emulsion membrane could be improved by decreasing the number of inner droplets in the emulsion drop as suggested by the simulation. These experimental confirmations of the suggested model led to a simple way of improving the separation selectivity of this separation technique.
