Preventing Hydrate Formation Problems at Storage Sites

Special to P&GJ  In natural gas storage facilities in underground salt caverns, hydrates can easily form in the pipes, clogging them and making regular measurement of the gas pressure difficult.   The copper ball valve enables safe and efficient operation. (Photo: Armaturenfabrik Franz, Schneider GmbH + Co. KG) To avoid crystal accumulations, there is the possibility of heating the gas—which, until now, was a technically complex procedure.   Depending on the composition of the gases, the threshold for the formation of hydrates is about 75 degrees F (24 degrees C). Above this temperature, such a process is unlikely. That is why t
