In their previous papers (this Journal, 14, 227 (1960); 26, 205 (1972); 27, 321 (1974)) the authors reported the isotherms of the quinary system NaCl-KCl-MgCl2-CaCl2-H2O at 25°C, 50°C and 75°C.
In this paper, equilibria of the ternary systems NaCl-CaCl2-H2O, KCl-CaCl2-H2O and the quatermary system NaCl-KCl-CaCl2-H2O at 110°C were studied.
This study was done to complete the equilibrium diagram of the five component system NaCl-KCl-MgCl2-CaCl2-H2O at 110°C, which would be useful for the calculation of isothermal evaporation of natural gas brine, ion exchange membrane brine etc.
Based on the data obtained by using the DTA, X-ray analysis, atomic absorption spectroscopy and chemical analysis, isotherms and invariant points of the ternary systems NaCl-CaCl2-H2O, KCl-CaCl2-H2O and the quaternary system NaCl-KCl-CaCl2-H2O were determined.
