Phase equilibria with hydrate formation in H2O + CO2 mixtures modeled with reference equations of state

Original language description

Formation of gas hydrates is an important feature of the water?carbon dioxide system. An accurate description of thermodynamic properties of this system requires a consistent description of both fluid and solid states and of their respective phase equilibria. In this study, we modified and refitted the gas hydrate model by A.L. Ballard and E.D. Sloan to combine it with highly accurate equations of state (EoS) in form of the Helmholtz energy and Gibbs energy for other phases formed in the water?carbon dioxide system, e.g., IAPWS-95 and IAPWS formulation for water ice Ih. Since the gas hydrate model uses the fugacity of the gas component in the coexisting phase as an input variable, the accuracy of the predicted phase equilibria was significantly improved by using highly accurate EoSs for coexisting phases. The new hydrate model can be used in a temperature range of 150?295 K and at pressures up to 500 MPa.
