The three-phase, hydrate-liquid-vapor (H-Lw-V), equilibrium conditions of the carbon dioxide gas hydrate with promoting materials cyclic ether compounds such as THF (tetrahydrofuran), 1, 4-dioxane and propylene oxide were experimentally determined at pressures range from 1.5 to 4.5 MPa with corresponding temperatures between 274 to 290 K. The concentrations of them were 1, 2, 3, 5 mol % for THF and 1, 3, 5, 10 mol % for propylene oxide. The phase behavior was similar to that of the hydrate system without this compound, but the equilibrium lines were shifted to right side of those of pure CO2.
