Abstract : In this work, we report ice-clathrate hydrate-gas equilibrium data (dissociation data) for the air, oxygen, nitrogen, carbon monoxide, methane, or ethane + water system. The equilibrium data for methane and ethane clathrate hydrates are compared with the equilibrium data reported in the literature to demonstrate the reliability of the isothermal pressure-search method used in our measurements. The equilibrium data generated for nitrogen and oxygen clathrate hydrates are compared with few sets of experimental data reported in the literature. It is shown that the existing ice-clathrate hydrate-gas equilibrium data reported in the literature for the nitrogen or oxygen + water system are not reliable. A comparison is finally made on the equilibrium conditions of air, oxygen, nitrogen, and carbon monoxide clathrate hydrates.
