摘要：

Liquid and gas mole fractions were obtained at three-phase H-Lw-V equilibrium for the CH4 + C2H6 + H2O system at experimental conditions ranging from 275.1 to 279.1 K and 0.76-2.87 MPa. To ensure the system reached equilibrium while sampling, gaseous mole fractions were compared to literature values and were found to correspond. The solubility of both methane and ethane along isotherms is reported at various pressures. The effect of thermodynamic parameters on equilibrium liquid mole fractions can be observed. Additionally, structure transitions between 51 and sII were found to influence solubility trends. While scarce in literature, experimentally obtained liquid mole fractions at three-phase equilibrium conditions provide further insights into multicomponent gas hydrate system properties and establish a solid foundation for future studies.
