n: a paraffin hydrocarbon, C4H10 , that is a gas in atmospheric conditions but is easily liquefied under pressure. It is a constituent of liquefied petroleum gas. See commercail butane, field-grade butane, normal butane.

a four carbon chain alkane, may be a liquid in the reservoir, but vaporizes as pressure is released. Part of the natural gas liquid components.

n: a gas-processing plant that is capable of producing natural gas liquid products, including ethane, at very low operating temperatures.

n: the reduction in volume of wet natural gas due to the removal of natural gas liquids, hydrogen sulfide, carbon dioxide, water vapour, and other impurities from the natural gas stream. See also shrinkage.

n pi: liquids recovered from natural gas in a gas processing plant and, in some situations, from field facilities. See natural gas liquids.

n: 1. residue gas remaining after recovery of natural gas liquids in a gasprocessing plant. 2. unprocessed gas containing few or no recoverable natural gas liquids. Also called dry gas.

a near dry gas, containing only a trace of condensate.

n: a natural gas liquid recovered from gas well gas in lease separators or natural gas field facilities. Consists primarily of pentanes and heavier hydrocarbons. Usually blended with crude oil for refining.

n pi: (NGL) those hydrocarbons liquefied at the surface in field facilities or in gas processing plants. Natural gas liquids include propane, octane, and natural gasoline.

The portion of the natual gas compounds that liquify at surface conditions.
