Hydrate-based gas separation (HBGS) is a new method for extracting helium from helium-rich natural (HNG). The ethane in HNG affects the thermodynamic equilibrium hydrate formation pressure (Peq), and Peq crucial to application of HBGS helium. In this work, HNGs with different contents (0.5 mol%, 1.0 10 mol%) solutions tetrahydrofuran (THF) (5 wt%, 19 at temperatures were experimentally investigated through isothermal search method. Ethane THF have competitive effect on formation. A model was proposed predict HNG–THF solution systems. can be quantitatively described, accurately predicted by work. average relative deviation predicting aqueous systems less than 3%. results study guide operating conditions optimization process.
