NGL are natural gas liquids that are naturally occurring elements found in natural gas. They include ethane, butane and propane. Natural gas liquids are considered to be valuable as separate products, and it's considered profitable to remove them from natural gases.
NGL are explained as components of natural gas that are separated from the gas state in the form of a liquid. This type of process occurs in gas processing plants or a field facility through adsorption, condensation, absorption or other methods. The natural gas liquids are classified according to their vapor pressure. Low vapor pressure is condensate, intermediate is a natural gas and high is liquefied petroleum gas.
