Submarine temperature, pressure, gas compositions, geothermal gradient and syngenetic water salinity control the depth of hydrate zone basement.Autochthonous bacteriogenic mod...
According to comparing various hydrate promotors and their experimental conditions,it indicates that methylcyclohexane is a good promotor to form st...
The ubiquity of phenanthrene series, chrysene series compounds, perylene and retene compounds in the sediment indicated that PAHs mainly came from the terrestrial plants.
And trapped inside the crystals of ice are individual molecules of methane that's what's in natural gas. All this makes gas hydrate pretty strange stuff.
If they form, it can be very catastrophic, because if you release sort of this methane hydrate plug, the methane can come out and essentially lead to an explosion.
Then there are minerals that might form often enough, but don’t stick around for very long -- methane hydrate crystals, for example, will just dissolve in air at standard pressure.
Not only does a gas stream contain water vapor that can freeze by itself, that water vapor can also combine with hydrocarbons to create hydrates that solidify at temperatures well above freezing.
