STRIPPING OF AMMONIA FROM AQUEOUS SOLUTIONS OF AMINO ACIDS AND INORGANIC IONS

Abstract

The stripping of ammonia from aqueous solutions of amino acids and strong electrolytes has been investigated both experimentally and theoretically. The experiments have been carried out in an isothermal stirred semibatch stripper. A good agreement between experimental data and model predictions has been obtained for all the examined operating conditions. The model accounts for all dissociation equilibria while it assumes ideal behavior for the liquid phase. It does not include any adjustable parameter, and so it can be readily extended to various systems of practical interest, such as those involved in the treatment of side-streams arising in the production of amino acids
