The formation and presence of clathrate hydrates could influence the composition stability planetary ices comets; they are at heart development numerous complex models, all which include necessary condition imposed by their curves, some cage occupancy or host-guest content hydration number, but fewer take into account kinetics aspects. We measure temperature-dependent-diffusion-controlled carbo...

The thickness of the free gas column below the base of the gas hydrate stability zone is a proxy for the pore pressure in the free gas bearing sediments underneath. In the study area the pore over-pressrues derived under this assumption range between 0 and 1430 kPa ± 30% which appear to be the typical maximum over-pressure that the gas hydrate sediments can withstand before hydro-fracturing occ...

Abstract Hydrate formation characteristics and hydrodynamic behavior have been investigated for mixture of methane–propane hydrate with pure water the amino acid lysine 1.5 wt% at 24.5 bars 2 °C. There were total 12 experiments full no baffle estimating induction time, rate formation, productivity power consumption. The outcomes showed that radial flow better compared to mixed ones due interact...

During Ocean Drilling Program (ODP) Leg 204, we will drill a transect of sites through the gas hydrate stability zone on the southern part of Hydrate Ridge on the Cascadia accretionary margin offshore Oregon. Massive hydrates are present at the seafloor there, and high-resolution threedimensional seismic data indicate a complicated subsurface plumbing system. The transect will cover two distinc...

The separation of azeotropic mixtures has conventionally been one the most challenging tasks in industrial processes due to fact that components mixture will undergo gas–liquid phase transition at same time. We proposed a method for separating azeotropes using hydrate formation as solid–liquid transition. feasibility hydrate-based is determined by analyzing crystal structure and chemical bonds ...

Hydrate-based Carbon dioxide (CO2) separation was widely concerned because of its simple process and low energy consumption. Mechanical stirring could promote gas-liquid-hydrate three-phase contact hydrate formation but consumed lots energy. Therefore, it necessary to develop more efficient technologies. Nickel foam (Ni–F) is an excellent hydrogen (H2) storage material with properties porous st...
