Evaporation solar pond from distilled ammonia waste liquid

To achieve energy conservation from distilled ammonia waste liquid in Qinghai Qaidam Basin,the isothermal balance method is used to determine the phase equilibrium data of NaCl-CaCl 2-H 2 O ternary system in 15℃. The isothermal phase diagram is drawn and the evaporation experiment is carried out. Technical route of energy-saving for preparing evaporation solar pond from distilled ammonia waste liquid is obtained.
