Hydrates

Hydrates in natural gas processing Routine operations Methane clathrates (hydrates) are also commonly formed during natural gas production operations, when liquid water is condensed in the presence of methane at high pressure.

It is known that larger hydrocarbon molecules like ethane and propane can also form hydrates, although longer molecules (butanes, pentanes) cannot fit into the water cage structure and tend to destabilise the formation of hydrates.

When the hydrates rise, the pressure in the annulus decreases and the hydrates dissociate into gas and water.
