Abstract

This paper reports pressure-temperature conditions for liquid + hydrate + vapor phase equilibrium of hydrate formed with deuterium oxide (D2O), CO2 and cyclopentane. The aim of this study is to obtain the equilibrium properties of the formed hydrate for the application to hydrate-based tritium separation process. Measurements with batch isochoric method were performed. The pressure and temperature ranges of measurement were from 1.63 MPa to 2.46 MPa and from 290.6 K to 293.4 K. The obtained results indicate that D2O + CO2+ cyclopentane hydrate is formed in milder conditions than H2O + CO2+ cyclopentane hydrate by 2.1 K at the given pressure conditions.
