Abstract

The technology of the deep-ocean CO₂ storage is expected to directly mitigate the source of the global warming. At deep-ocean condition above 4.45 MPa and below 283 K, the CO₂ clathrate hydrate crystals are formed as membrane at the interface between the liquid-water phase and the liquid-CO₂ phase. Since the strength and the thickness of the hydrate membrane are crucial to the storage period, it is important to experimentally measure the mechanical characteristics of the CO₂ hydrate membrane and the hydrate droplet. In the present study, the CO₂ hydrate membrane thickness is measured by using the laser-light interference method. It is clarified that the present method by using the beam light interference method is applicable to measure the CO₂ hydrate membrane. The hydrate membrane thickness is estimated to be about 7 μm∼12μm at 10MPa and 275 K∼283 K. It is also clarified that thickness of the CO₂ hydrate membrane is in proportion to the temperature.
