Methane Hydrate Crystal
Mining -- Geologists have discovered frozen natural gas crystal deposits on the ocean bottom.
If the cluster is big enough and remains clustered long enough, it rearranges into a low-energy, highly ordered solid state called a hydrate crystal.
These delay hydrate crystal nucleation in water passing through a pipe even while the fluids are at high pressure and at temperatures far below the natural hydrate formation temperature.
When the seabed water temperature falls, hydrate crystals
can form in the pipeline and these could restrict the flow of gas and may seriously damage the pipelines.
The hydrate crystals
have complex, three dimensional structures in which the water molecules form a cage and the guest molecules are entrapped in the cages.
When ice-like methane hydrate crystals
formed inside the massive 100-ton box, forcing its removal, plans were made to install a much smaller two-ton box called a top hat.
