Ice - Clathrate Hydrate - Gas Phase Equilibria for Argon + Water and Carbon Dioxide + Water Systems

In this communication, we report ice - clathrate hydrate - gas equilibrium data (dissociation data) for the argon + water and carbon dioxide + water systems in the temperature ranges of (264.3-271.2) and (260.2-270.7) K, respectively. The equilibrium data for carbon dioxide 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 work. The equilibrium data generated for argon clathrate hydrates are compared with few sets of experimental data reported in the literature. A comparison is finally made on the equilibrium conditions of argon, air, oxygen, nitrogen and carbon monoxide clathrate hydrates.
