Prediction of high-pressure gas solubilities in aqueous mixtures of electrolytes

The main purpose of thos work has been to provide a means for predicting high-pressure gas solubilities based on low-pressure experimental information for the gas-salt-water system. In the new model gas-salt interactions are taken into account by a single temperature- and composition independent parameter.

This parameter is determined from low-pressure salting out constants. This approach results in fine predictions of high-pressure gas solubilities, although the salting out effect may be slightly overpredicted at high salt concentrations.
