| Abstract: | On the basis of Pitzer theory of electrolyte solution and the Pitzer volumatic parameters provided by Oakes and with the help of computer, phase equilibrium date and isodensity on the unsaturated region of NaCl - CaCl2 - H2 0 system at 25 t are calculated. According to these date, a phase diagram with isodensity is drawn, and the salt crystallization low of waste ammonia liquor from soda - making by solvay method is investigated. |
