Thermodynamic models to characterize multicomponent aqueous solutions for conditions (T £ 250°C; P » 1 atm) where the principal variation of the liquid density phase free energy is due to solute concentration changes.

Run TEQUIL


(I) Equation of State for the NaCl-H2O-CO2-CH4 system that calculates PVTX and phase equilibrium data from 300° to 1000°C and from 0 to 6000 bar (PVT data) or 3000 bar (phase equilibria). Equation of State for the H2O-CO2-CH4 system that calculates PVTX and phase equilibrium data from 50° to 1000°C and from 0 to 3000 bar.

(II) Equation of State for the H2O-CO2-CH4 system that calculates PVTX and phase equilibrium data from about 1.3 times the critical temperature of the least volatile component to 2000 K and from 0 to 100 kbar.

Run GEOFLUIDS


Enthalpy of Natural fluids in the NaCl-H2O and H2O-CO2-CH4 systems.

Run GEOHEAT


We develop advanced chemical model technologies that correctly predict resource and process chemistry over wide ranges of composition, temperature and pressure. The equation of state (EOS) frameworks and computer technology we use are capable of handling many complicated chemical reactions, succinctly summarizing large amounts of experimental data and extrapolating to desired PVTX conditions. Modecular level simulation methods we develop can supply necessary thermodynamic information and more advanced theoritical structures can yield better extrapolation properties.
