Abstract: In SAFT1-RPM approximations of CO2−H2O and CO2−H2O−NaCl systems, relevant to oil recovery and CO2 sequestration, CO2 is modeled as a molecule with three association sites, two sites of type O and one site of type C. H2O is modeled as a molecule with four association sites, two sites of type O and two sites of type H. The salt is modeled as a molecule composed of two charged, but nonassociating, spherical segments, of which one represents the cation and one represents the anion. For the CO2−H2O system, only one… Show more

“…In the -γ φ approach, an equation of state (EOS) is used to describe the non-ideality of the CO 2 -rich phase and Henry's law or an excess molar Gibbs free energy (G E ) model is used to describe the non-ideality of the H 2 O-rich phase. While in the -φ φ approach, an EOS is used to describe the non-ideality of both phases [51].…”

“…However, the predicted water content in the CO 2 -rich vapour phase deviated from experimental data, especially at low temperatures and high pressures, which may be due to the assumption of non-association sites between water and CO 2 , and non-effect of the temperature on square-well potential parameters. Ji et al [51] represented the density and the composition of the equilibrium phases in the CO 2 -H 2 O system from 285 to 473K and up to 60MPa by using SAFT1 EOS. The calculated results agree with the experimental data in the temperature range of 288.15 to 373.15K.…”
