Solubility of mixture of nonpolar gases in water

The Solubility of Binary Mixed Gases by the Fluctuation Theory

“…This topic has attracted the attention of both experimentalists and theoreticians. [1][2][3][4][5][6][7][8] Whereas the solubilities of many individual gases in liquids have been precisely measured, [9][10][11] those of mixed gases have rarely been determined; even complete information about the solubility of air in water in a wide range of pressures and temperatures is not available. 9,10 So far, there is no rigorous method for predicting the solubilities of gaseous mixtures in liquids; only an empirical method for mixtures of hydrocarbons has been suggested.…”

“…The removal of acid gases from natural gas streams; the solubilities of hydrocarbons and natural-gas components such as CO 2 and H 2 S in water under high-pressure/high-temperature conditions; and the solubilities of air and other mixed gases in water, blood, seawater, rainwater, and many other aqueous solutions are a few examples for which information about the solubility of mixed gases in a solvent is needed. This topic has attracted the attention of both experimentalists and theoreticians. − Whereas the solubilities of many individual gases in liquids have been precisely measured, − those of mixed gases have rarely been determined; even complete information about the solubility of air in water in a wide range of pressures and temperatures is not available. , So far, there is no rigorous method for predicting the solubilities of gaseous mixtures in liquids; only an empirical method for mixtures of hydrocarbons has been suggested . As mentioned in the literature, the usual methods for predicting vapor−liquid equilibrium, such as the Wilson, NRTL, and UNIQUAC approaches, cannot be straightforwardly extended to the solubility of mixtures of two supercritical gases.…”
