Abstract: In this study, the simple gas hydrate equilibrium conditions of methane and carbon dioxide in water were measured by using high pressure micro DSC (why is the advantage). The technique was chosen because it is economic, fast and accurate. In this study, the methane hydrate equilibrium conditions were measured at pressure between 35-112 bar and temperature between 276-288 K. In addition, the carbon dioxide hydrate equilibrium conditions were measured at pressure between 15-37 bar and temperature between 274-282.5 K. The measured data was compared to the available literature data and the AADT % between the measured data and predicted model was calculated. Good agreements were obtained between the measured and literature data. The AADT% between the measured data and predicted models is less than 0.07% for CH4 hydrate and 0.15% for CO2 hydrate.
