Thesystem involves more than 10 components of electfolytes and molecules. In this paper, experimentswere cAned out to measure vapor phase partial pressures of COZ and NH3. The experimental conditionscover carbonation degree of 0. 10.9, temperature of 30-70℃, and ion strength of 4.5-6 mol. （kgH2O）-1.A simplified Pitier equation was employed to calculate activity coefficients of ion and molecularcomponents, and the binary interaction parameters were regressed from the experimental data. Variationof concentration of each component during carbonation process was computed and analyzed accordingto the proposed thermodynamic model.展开更多
