PHREEQC version 3 calculates pressure effects and gas solubility at (very) high pressures:

Pressure effects on solubility gas solubilities aqueous molar volumes solution densities gas solubilities scale solubilities Belousov's reaction

Advanced PHREEQC options include multicomponent diffusion, diffuse layer calculations, colloid transport, CD-MUSIC, and more...:
