APPLICATION OF PENG-ROBINSON EQUATION TO HIGH-PRESSURE AQUEOUS SYSTEMS CONTAINING GASES AND SODIUM CHLORIDE
A novel approach is proposed for modeling vapor-liquid equilbria in systems containing aqueous NaCl and supercritical gases. The Peng-Robinson equation of state is used for all species, with that salt treated as a hypothetical liquid component. To correctly model the highly non-ideal liquid solution, a two-fluid model is used for the mixing rules in the equation of state. Effective pure-component parameters are reported for NaCl as well as binary interaction parameters for all possible binaries. Representation of high-pressure phase equilbria data show good agreement with experimental data. The principal advantage of this approach is the ability to treat high pressure systems containing non-volatile salts, while maintaining the simplicity of a cubic equation of state.
