natural gas liquids(Liquids obtained during natural gas production, including ethane, propane, butanes, and condensate (Bab GPI). There is no precise definition. NGLs are essentially those hydrocarbons which can be extracted in liquid form from natural gas as produced. Typically ethane, LPG, and Pentanes will be the predominant components, but there will be some heavier hydrocarbons present. (Bab Oil and Gas Field Glossary ) Alexander Demidov)
