Thermodynamic models for vapor–liquid equilibria of nitrogen+oxygen+carbon dioxide at low temperatures

Jadran Vrabec, Gaurav Kumar Kedia, Ulrich Buchhauser, Roland Meyer-Pittroff, Hans Hasse
2009 Cryogenics (Guildford)  
Two such thermodynamic models, the Peng-Robinson equation of state (EOS) and a model based on Henry's law constants, are proposed for the ternary mixture N2+O2+CO2.  ...  On the basis of this model, the Henry's law constants of N2 and O2 in CO2 are predicted by molecular simulation.  ...  On the basis of existing models for pure fluids, molecular modelling of mixtures reduces to specifying the interaction between unlike molecules.  ...
