Abstract
A systematic study of membrane-assisted extraction of naphthenic acids from hydrocarbon fractions by aqueous caustic soda using both porous and nonporous membranes is reported. The effects of hydrodynamic facto rs, concentration of naphthenic acids and caustic soda, and temperatur e on the transmembrane flux are discerned. The film model is used to d etermine the intrinsic mass transfer characteristics of the membranes.
