Abstract

The thermodynamics of solution of voletile cormponents in water is reviewed and expressed both in terms of the Henry's constant and the vapor-liquid distribution coefficient. The procedures required to calculate these quantities from experimental data are described, as are those required to estimate solubilities in realistic systems from Henry's constants or distribution coefficients. Emphasis is given to calculations for high-temperature aqueous systems as encuntered in the power industry and in geochemistry. Correlations are given for the Henry's constant and vapor-liquid distribution coefficient for 14 common gases in water up to the highest temperatures at which data are available. Finally, the effects of dissolved electrolytes on aqueous gas solubility are briefly reviewed.
