The phase equilibrium condition for carbon dioxide and methane mixture were measured experimentally at constant pressure. The experiments were conducted at temperature from 272.36 to 283.56 K and at pressure 15, 20, 26, 35 and 50 bar. The composition of hydrate and vapor was analyzed at the pressure 20, 26 and 35 bar. The composition of carbon dioxide in hydrate phase decrease with increasing pressure. The thermodynamic model for the three-phase equilibrium condition of gas mixture is capable of the calculation of the hydrate dissociation pressure as well as compositions of vapor phases. Calculated results have good agreements with the experimental results.
