Solubility Measurements for the N2 + CO2 + H2O System under Hydrate-Liquid-Vapor Equilibrium

Equilibrium liquid and gas mole fraction measurements were taken at hydrate liquid vapor equilibrium for the N-2 + CO2 + H2O system. Experimental conditions ranged from 275.1 K to 279.2 K and from 2.7 MPa to 14 MPa. Gaseous mole fractions were compared to literature values to validate that equilibrium was reached. The effect of temperature and pressure changes on the solubility of both gas hydrate formers along isotherms is reported. The thermodynamic region associated with a hydrate structure change affected solubility trends.
