Abstract

Water solubility at 25 °C was studied in the four-component water-salt system comprised of sodium and calcium sulfates and hydrocarbonates in order to determine the concentration parameters of solution and crystallization of the constituent salts and to experimentally verify the phase equilibria in the geometric images of the system predicted previously by the translation method. The prediction of possible phase equilibria in geometric images of the system, followed by plotting its phase diagram, appreciably decreases the time and material costs of experimentation and improves the reliability of results. Our results can serve both as reference information and as a scientific base for optimizing the parameters of natural and artificial processes, in particular, the recycling of salt from liquid waste of aluminum production facilities.
