Prevent methane hydrate formation in natural gas valves

05.01.2013  |  Glaun, A. ,  GE Oil & Gas, Avon, MassachusettsShahda, J. ,  GE Oil & Gas, Avon, Massachusetts

The discussion here focuses on the thermodynamics involved and on the requirements for a successful natural gas valve application in which the incidences of hydrate formation and icing of the valve are reduced.

Keywords: [methane hydrates] [natural gas] [valves] [pipelines]

Gas flow across a control valve is considered a classic “throttling” process that is defined by energy not being added or extracted from the process gas as it traverses the valve. Therefore, total enthalpy is preserved, entropy increases and the process is thermodynamically irreversible.
