Abstract
An experimental comparative analysis of various factors involved in the separation of styrene‐ethylbenzene mixtures by liquid membrane permeation was performed.The choice of the proper surfactant and the influence of the ratio surfactant/solvent/feed and of the operating parameters were investigated.An attempt is made to interpret the experimentally determined characteristics of the system on the basis of a diffusive model adapted to this kind of separation.
