Hydrates are prevented by insulating pipelines, dehydrating the gas, treating the water in the pipeline with large quantities of freezing point depressants such as methanol or glycol, or treating the water with low doses of a kinetic hydrate inhibitor. These measures are intended to keep the treated pipeline hydrate-free at all times.
