The present work deals with the fractional crystallization of salts from seawater. New experimental data for the crystallization sequence and the liquid phase ion molalities for aqueous model solutions that contain the major seawater components are presented. For describing the studied electrolyte solutions, the Pitzer model was used with parameters adopted from the literature. This fluid property model was combined with an equilibrium model of the fractional crystallization. The comparison of the simulation results with experimental data from both the literature (for seawater) and this work (for model solutions) shows generally good agreement for seawater-like solutions, but also reveals limitations of the model.     «
