Methane storage and transport via structure H clathrate hydrate
… thesis examines the prospect of structure H (sH) hydrate to be exploited for methane storage. The methane content in the hydrate, hydrate kinetics and conversion rates are areas of particular importance. Experiments and theory are employed at the macroscopic and molecular levels to study the …

Studies on the rheology of ice and clathrate hydrate slurries formed in situ from water-in-oil emulsions
Includes bibliographical references (pages 151-158).

Hydrate-phobic surfaces
Clathrate hydrate formation and subsequent plugging of deep-sea oil and gas pipelines represent a significant bottleneck for ultra deep-sea production. Current methods for hydrate mitigation focus on injecting thermodynamic or kinetic inhibitors into the flow, heating the pipe walls, or managing …

Probing Matter with Photons, Electrons and Neutrons: A Study of Water and Flax
… in the mechanism of ice transformation. Standard clathrate hydrate stability relations, between pressure and temperature, imply various clathrates are unlikely to form under high vacuum. However, with appropriate mixtures and heating rates, several improbable hydrates have been formed. …

Capillary forces and wetting dynamics by diffuse-interface modeling
… relevant to the petroleum industry, where gas hydrates forming large clusters in subsea pipelines during crude oil transportation is a major concern. The dynamics of such systems is also of great interest from a fundamental perspective. Indeed describing non-equilibrium situations involving a …

… mode. The formation and degradation of imperfect clathrate- hydrates structures type I could be observed in the case of pure water, and in mixtures of ethanol and water with volume ratios of 80/20, 70/30, and 50/50, but not in the case of pure ethanol and in mixtures with a volume ratio of 90/10. …
