Open questions on methane hydrate nucleation [PDF]
The commercial use of natural methane hydrate is hampered by several open questions that remain regarding hydrate formation. Here the authors comment on past interpretations and aim to provide a roadmap for developing a predictive theory of methane ...

Stress‐Induced Melting Controlled Failure Mechanisms of Methane Hydrate [PDF]
Methane hydrate, a kind of nonstoichiometric crystalline, attracted worldwide attentions as a promising substitute energy. Its Dissociation is thought to be dominated by thermodynamic conditions, yet its intrinsic deformation behavior remains elusive ...

Dataset for the new insights into methane hydrate inhibition with blends of vinyl lactam polymer and methanol, monoethylene glycol, or diethylene glycol as hybrid inhibitors [PDF]
Three-phase equilibrium conditions of vapor–aqueous solution–gas hydrate coexistence for the systems of CH4–H2O–organic thermodynamic inhibitor (THI) were experimentally determined.

Experimental Research on the Mechanical Properties of Methane Hydrate-Ice Mixtures
The mechanical properties of methane hydrate are important to the stability of borehole and methane extraction from a methane hydrate reservoir. In this study, a series of triaxial compression tests were carried out on laboratory-formed methane hydrate ...

Influence of temperature on methane hydrate formation. [PDF]
AbstractDuring gas hydrate formation process, a phase transition of liquid water exists naturally, implying that temperature has an important influence on hydrate formation. In this study, methane hydrate was formed within the same media. The experimental system was kept at 1.45, 6.49, and 12.91 °C respectively, and then different pressurization modes ...

Transformations in methane hydrates [PDF]
Detailed study of pure methane hydrate in a diamond cell within situoptical, Raman, and x-ray microprobe techniques reveals two previously unknown structures, structure II and structure H, at high pressures. The structure II methane hydrate at 250 MPa has a cubic unit cell ofa= 17.158(2) Å and volumeV= 5051.3(13) Å3; structure H at 600 MPa has a ...
