In the current study, theoretical behavior of commercially available hollow fiber membrane contactor modules has been presented to investigate the extraction efficiency and mass transfer solute flux. It was aimed to separate the selected aroma compounds from aqueous streams with an organic solvent, hexane at ambient temperature. It was found from the results that distribution affinity of the solute with the solvent, diffusivity of solute and the hydrodynamics strongly affect the flux and extraction efficiency. Moreover, the geometry of the hollow fiber membrane contactor also plays an important role in the recovery of the solute from aqueous solution.
