Hydrate-Aqueous Liquid-Vapor Equilibrium (H-LW-V) for binary CO2/H2 Mixture in Aqueous Solutions of Water and Tetrahydrofuran

Hydrate - aqueous liquid - vapor equilibrium conditions of clathrate hydrate formed from mixtures of
carbon dioxide and hydrogen in aqueous tetrahydrofuran solutions (5.6 mol%) at different mixing ratios of CO2 and
H2 are presented. All the phase equilibrium measurements are performed by using a Cailletet apparatus. The
experimental temperature range is from 275 up to 295 K and the pressure range is from 1 up to 10 MPa. The
addition of THF has been proven to significantly reduce the hydrate equilibrium pressure at a specified
temperature. Moreover, the hydrate formed in the aqueous THF solutions is found to be more thermally stable
compared to that of in water only. Also, the equilibrium conditions are dependent on the ratio of CO2 and H2 in the
mixture.
