Phenols occur as toxic contaminants in effluent waters from industries such as oil refining, coke and coal processing, phenolic resin manufacture, and several other chemical and metallurgical operations. This paper reports experimental data on the removal of phenol from aqueous solutions using emulsion liquid membranes in a microporous hollow-fiber extractor. The hollow-fiber extractor appears to offer significant advantages over conventional liquid-liquid contactors for this separation because emulsion leakage and swell are practically eliminated even when treating high phenolic feeds. The overall mass-transfer coefficients are seen to be more strongly dependent on the phase flow rates among the parameters studied. The experimental mass-transfer coefficients have been predicted by a resistance-in-series model.
