Topological crystallography of gas hydrates

Acta Crystallographica Section A Foundations and Advances, 2015
A new approach to the investigation of the proton-disordered structure of clathrate hydrates is presented. This approach is based on topological crystallography. The quotient graphs were built for the unit cells of the cubic structure I and the hexagonal structure H.

Fundamentals and Applications of Gas Hydrates

Annual Review of Chemical and Biomolecular Engineering, 2011
Fundamental understanding of gas hydrate formation and decomposition processes is critical in many energy and environmental areas and has special importance in flow assurance for the oil and gas industry. These areas represent the core of gas hydrate applications, which, albeit widely studied, are still developing as growing fields of research ...

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 ...

Effect of gas hydrates and hydrate formers on invertase activity

Archives of Biochemistry and Biophysics, 1969
Abstract Gas hydrates are inclusion compounds of the clathrate or cage type, many of which are stable above 0 °. The object of this study was to determine the effects of some gas hydrates and hydrate formers on invertase activity. It was shown that invertase activity: (1) was not significantly influenced by the increase in solute concentration that ...

Pore occupancy of gas hydrate

Physical Review E
Methane hydrate deposits are one of the largest fractions of hydrocarbons in the Earth's crust. They are found mainly in ocean sediments, and the configuration of the deposits-at the largest (kilometer) and smallest (micrometer) scales-determines how and when gaseous methane is released.

CONDİTİONS OF GAS HYDRATE FORMATİON İN MAİN GAS PİPELİNES AND METHODS OF GAS HYDRATE CONTROL

Power Engineering Problems
Ensuring reliable operation of the main gas pipeline is one of the most urgent issues of hydrocarbon transportation in the modern era. Thus, as a result of certain geological-technological and temperature environmental impacts during the operation of the main gas pipeline there are difficult to eliminate complications due to the formation of gas ...

GAS HYDRATES IN THE OCEANS

International Geology Review, 1987
On the whole, the formation of gas hydrates in the ocean sediments is determined by a large number of factors: the change in temperature and pressure with depth in the oceans, the magnitude of the heat flow, geothermal gradient, and thermal-conductivity of the sediments, the composition of the sediments and gas, the mineralization of the sea water, etc.
