What is NGL?

The Natural Gas Liquids transports NGL products from gas production plants and refineries to wholesalers, retailers and brokers across North America through intricate rail and pipelines. Natural Gas Liquids, including ethane, propane, butane, and sulfur, which are derivatives of natural gas, extracted during gas refining.

Natural Gas Liquids: The Basics

Natural Gas, the source of Natural Gas Liquids is a natural mixture of gaseous hydrocarbons found in the ground or obtained from specially driven wells. The composition of natural gas varies in different parts of the world. Its chief component, methane, usually makes up from 80% to 95% its composition. The balance is composed of varying amounts of ethane, propane, butane, and other hydrocarbon compounds.

Products that fall under the 'NGL' classification consist of:


Ethane

A continuous-chain alkane. As a constituent of natural gas, it is used for fuel. It can be prepared by cracking and fractional distillation of petroleum.

Propane

A colorless, gaseous alkane. It is readily liquefied by compression and cooling. It melts at -189.9°C and boils at -42.2°C. Propane occurs in nature in natural gas and (in dissolved form) in crude oil; it is also a byproduct of petroleum refining. It is used chiefly as a fuel. For this purpose it is sold compressed in cylinders of various sizes, often mixed with other hydrocarbons, e.g., butane. Propane fuel is used in a type of cigarette lighter, as a motor vehicle fuel, in portable stoves and in portable lamps.

Normal Butane

A hydrocarbon obtained from natural gas or by refining petroleum. It can be liquefied at room temperature by compression. There are two structural isomers of butane. In normal butane, or n-butane, the four carbon atoms are joined in a continuous, unbranched chain; in isobutane, or 2-methylpropane, three of the carbon atoms are joined to the fourth by single bonds, resulting in a branched structure. The two isomers differ in certain chemical and physical properties; for example, liquid n-butane has a higher boiling point (-0.6°C) at atmospheric pressure than that of liquid isobutane (-10.2°C).

Iso-butane

A hydrocarbon obtained from natural gas or by refining petroleum that is used in refinery alkylation. (See definition above.)

Natural Gasoline / Condensate

A gasoline blending component used as a refinery intermediate feedstock, crude diluent, and in chemical applications.

Sulphur

Primarily used in the manufacture of agricultural fertilizers and as an industrial feedstock.
