THE THERMODYNAMIC MODELING OF THE OPEN PHASE PROCESSES (THE EVAPOURATION AND CRYSTALLIZATION) IN MULTI-COMPONENT WATER-SALT SOLUTIONS

The object of investigation: the fourfold mutual galurgic system Na*99+, Mg*99+, HCl*99-, SO*004-H*002O in the interval of temperatures (25 to 0) degrees C. Offered and checked has been the original unrecursive algorithm of design of the composition and mass of the egally-balanced coexisting liquid and solid phases in the multi-component water-electrolyte systems. The curves of open evapouration and crystallization of the studied systems allow to determine not only the compositions of the equally-balanced coexisting phases, but its masses, depending on the quantity of the left solution (evapouration) or temperature of the heterogeneous system (crystallization). The selection of the optimum diagrams of extraction and processing of salts from the nature salt objects of the chloride-sulphate type has been performedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
