Natural Gas Separation by Gas Hydrate Crystallization Technology: Calculation of Gas Hydrate Distribution Coefficients

Chemistry and Technology of Fuels and Oils, 2023
This work considers the possibility of separating the natural gas from the Orenburg field using gas hydrate crystallization technology to purify methane from impurities. The effect of the mixture composition, process temperature, and pressure on the separation efficiencyof the gas mixture CH4 - C2H6 - C3H8 - i-C4H10 - н-C4H10 - C5H12 - N2 - H2S - CO2 ...

Natural Gas Hydrate Dissociation

2012
Experimental study of natural gas hydrate dissociation can provide a theoretical basis and technical reserves for future hydrate exploitation. Hydrate dissociation includes the thermodynamic and dynamic processes. Once thermodynamic conditions of the dissociation are satisfied, the dynamics plays a significant role for hydrate dissociation.

Natural Gas Hydrate: Environmentally Responsive Sequestration of Natural Gas

2013
Pleistocene glacial sediments will predominantly host NGH, and possibly only those to depths of no more than 1 km. Older sediments will likely be buried too deeply to host NGH. Each glacial episode would have produced a suite of sediments related to the onset and glacial maximum period and especially during the onset of the following interglacial ...

Natural Gas Evolution in a Gas Hydrate Melt: Effect of Thermodynamic Hydrate Inhibitors

The Journal of Physical Chemistry B, 2016
Natural gas extraction from gas hydrate sediments by injection of hydrate inhibitors involves the decomposition of hydrates. The evolution of dissolved gas from the hydrate melt is an important step in the extraction process. Using classical molecular dynamics simulations, we study the evolution of dissolved methane from its hydrate melt in the ...

Hydrate petroleum system approach to natural gas hydrate exploration

Petroleum Geoscience, 2014
Natural gas hydrate (NGH) is a solid crystalline material composed of water and natural gas (primarily methane) that is stable under conditions of moderately high pressure and moderately low temperature found in permafrost and continental margin sediments.
