Abstract

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 CO(2) and H(2) 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 CO(2) and H(2) in the mixture.
