Description
Natural Gas is primarily Methane and also some Ethane with small quantities of entrained heavier fractions,such as Propane, Butane, etc. These, and others, are readily condensed from the Natural Gas flow and are known as Natural Gas Liquids, or NGL's, as distinct from Liquid Natural Gas (L.N.G.) which is Methane/Ethane refrigerated to the liquid state. NGL may be produced from condensate reservoirs.
