Aqueous liquid membranes – State of the art. Use of emulsion liquid membranes with an aqueous membrane phase is a promising technique for the separation of hydrocarbons, if distillation is difficult or impossible. Intensive investigations on aqueous membranes during the past five years have increased our knowledge of the mass transfer mechanism which exploits different solubilities and diffusivities for the separation of hydrocarbons. The influence of the most important process parameters on the selectivity of the separation and on an overall mass transfer coefficient, serving as a measure of the mass transfer rate, are discussed. Possible applications and further developments are presented.
