Key Terms Definition
Natural Gas Liquids Those hydrocarbons in natural gas which are separated from the gas through the processes of absorption, condensation, adsorption, or other methods in gas processing or cycling plants. Generally such liquids consist of propane and heavier hydrocarbons and are commonly referred to as condensate, natural gasoline, or liquefied petroleum gases. Where hydrocarbon components lighter than propane are recovered as liquids, these components are included with natural gas liquids.
Natural Gas Processing Plant A facility designed to recover natural gas liquids from a stream of natural gas which may or may not have passed through lease separators and/or field separation facilities. Another function of the facility is to control the quality of the processed natural gas stream. Cycling plants are considered natural gas processing plants.
Plant Liquids Those volumes of natural gas liquids recovered in natural gas processing plants.
Production, Plant Liquids The volume of liquids removed from natural gas in natural gas processing plants or cycling plants during the report year.
