Explain the mechanism of hydrate formation and how glycol dehydration prevents it.

Hydrate formation is a phenomenon where water molecules and light hydrocarbon molecules (such as methane, ethane, propane, and butane) combine under specific temperature and pressure conditions to form a solid, ice-like crystal structure. These hydrates can plug pipelines, valves, and other equipment in natural gas processing and LNG plants, leading to flow restrictions, equipment damage, and operational disruptions. The driving force for hydrate formation is the attraction between water molecules and hydrocarbon molecules, which causes them ....
