The performance of membrane contactors to carry out liquid-liquid extraction and back-extraction for the recovery of amino acids (phenylglycine and aspartic acid) from dilute aqueous solutions has been investigated in the present work. The membrane assisted liquid extraction is a hybrid process which allows the integration in only one unit of the two steps involved in liquid-liquid extraction. This study looks closely at two amino acid models in increasing use nowadays: phenylglycine and aspartic acid. The effect of the stripping phase on the recovery yield was investigated. The viability of the integrated process of recovery and separation of ?-phenylglycine and aspartic acid from the dilute aqueous solutions was studied. The values of the mass transfer coefficients (overall and individual) were estimated by using a simple mathematic model. The influence of hydrodynamics (Reynolds number) on the overall mass transfer coefficients was also analyzed.
