Phase equilibrium condition measurements in carbon dioxide clathrate hydrate forming system from 199.1 K to 247.1 K

This paper reports ice + vapor + hydrate three-phase equilibrium condition measurements in CO₂ + H₂O system at the temperatures from 199.1 K to 247.1 K. The phase equilibrium pressures measured in the present study are from 34.3 kPa to 406.6 kPa. The measurements were performed using the batch, isochoric method. The results of the present measurements complement the lack of the literature data on the phase equilibrium conditions at the above temperature range and contribute to CO₂ hydrate-related environmental issues and technologies below the water freezing temperature such as Martian environment, fire extinguisher and working media of power generation system.
