Abstract
The isothermal evaporation of aqueous solutions containing calcium, magnesium, and sodium carbonates, phosphates, sulfates, and chlorides was studied by physiochemical simulation methods. The equilibrium composition of the Ca(HCO3)2-Mg(HCO)2-H3PO4-H2SO4-NaCl-CO2-H2O system was calculated for T = 25°C, pCO2 = 10−1 − 103 Pa, pH 7.7–9.4, solution concentration factors of 1–10, H2SO4 concentrations of 10−4−9 × 10−4 mol/(kg H2O), an H3PO4 concentration of 2 × 10−5 mol/(kg H2O), and a NaCl concentration of 10−3 mol/(kg H2O). Conditions were determined for calcium precipitation as calcite, dolomite, gypsum, and hydroxylapatite. The results of simulation were used in the development of commercial-scale methods for stabilizing cooling solutions in circulating water supply systems.
