N2 - An attempt was made to separate non-polar components from the polar fractions in kerosene using modified environments including the addition of polar solvents and surfactants. The solvent extraction process was based on the formation of an emulsion liquid membrane (ELM) which facilitates the separation. It was demonstrated that even a complex hydrocarbon mixture could be separated by ELM techniques if a facilitating agent (N-methyl pyrrolidone, NMP) was used in conjunction with high HLB surfactants (Tween 80). Low HLB value surfactants acted against the separation of polar compounds but participated in separation of apolar compounds.
