Different Mechanism Effect between Gas-Solid and Liquid-Solid Interface on the Three-Phase Coexistence Hydrate System Dissociation in Seawater: A Molecular Dynamics Simulation Study

Energies, 2017
Almost 98% of methane hydrate is stored in the seawater environment, the study of microscopic mechanism for methane hydrate dissociation on the sea floor is of great significance to the development of hydrate production, involving a three-phase ...

Influence of temperature on methane hydrate formation [PDF]

Scientific Reports, 2017
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 ...

Molecular Simulations of Methane Hydrate Nucleation

ChemPhysChem, 2010
Gas hydrates have been known for 200 years or more and the nature of these interesting solids remained hidden until crystallographic studies some 140 years later revealed that they were crystalline guest–host materials classified as clathrates. [1] The discovery of vast quantities of natural gas hydrate in sediment offshore on the continental margins ...

Specific Ion Effects of Chaotropic and Superchaotropic Anions Probed by Raman Hydration‐Shell Spectroscopy

Angewandte Chemie, EarlyView.
The vibrational frequencies of “dangling” water O─H bonds can be determined by Raman hydration‐ shell spectroscopy and used to differentiate chaotropes from kosmotropes and hydrophobes. Dangling O─H bonds are also detected around superchaotropic anions of the borate cluster type (B12X122−; X = H, F, Cl, Br, and I) but their frequencies do not directly ...

In situ benthic fluxes from an intermittently active mud volcano at the Costa Rica convergent margin [PDF]

, 2005
Along the erosive convergent margin off Costa Rica a large number of mound-shaped structures exist built by mud diapirism or mud volcanism. One of these, Mound 12, an intermittently active mud volcano, currently emits large amounts of aqueous dissolved ...
