Abstract: The prevention of hydrate formation or freezing in the gas industry is an old problem with every company experiencing it at one time or another. The removal of all the water vapor content from the gas is the perfect solution but is not economically feasible. In gathering systems, warm saturated gas comes from the formation along with free water and condensate. Gas hydrates appear much like wet snow, therefore causing it to pack solidly in pipelines, regulators, meters and other equipment, thus causing flow stoppage. These hydrates will form at temperatures well above 32 degrees F. if the pressure and water content is high enough. Fig. 1. Since regulation and measurement is still necessary under these adverse conditions, steps must be taken to minimize the problem. The most common methods will be covered in this paper.
