The alkanes have two main commercial sources: petroleum (crude oil) and natural gas. An alkyl group is an alkane-based molecular fragment that bears one open valence for bonding. They are generally abbreviated with the symbol for any organyl group , R, although Alk is sometimes used to specifically symbolize an alkyl group (as opposed to an ...
A gas pipeline compressor station. Gas is vented by design from the seals of some gas compressor equipment. In gas fields, acquiring non-associated petroleum gas (i.e. another form of raw natural gas) is the primary financial objective, and very little is unwanted compared to the gas produced in oil fields or coal mines.
Natural gas burning on a gas stove Burning of natural gas coming out of the ground. Natural gas (also called fossil gas, methane gas, or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane (95%) [1] in addition to various smaller amounts of other higher alkanes.
Methane is the predominant component of natural gas. C 6 through C 10 alkanes, alkenes, cycloalkanes, and aromatic hydrocarbons are the main components of gasoline, naphtha, jet fuel, and specialized industrial solvent mixtures.

It shows various unit processes converting raw natural gas into gas pipelined to end users. The block flow diagram also shows how processing of the raw natural gas yields byproduct sulfur, byproduct ethane, and natural gas liquids (NGL) propane, butanes and natural gasoline (denoted as pentanes +).
Schematic process flow diagram of a typical facility for processing raw natural gas to produce pipeline sales gas. Legend: Located at gas wells Located at gas processing plant; Red indicates final sales products; Blue indicates optional unit processes available; Notes: Condensate is also called natural gasoline or casinghead gasoline.
The process flow diagram below depicts a typical semi-regenerative catalytic reforming unit. Schematic diagram of a typical semi-regenerative catalytic reformer unit in a petroleum refinery. The liquid feed (at the bottom left in the diagram) is pumped up to the reaction pressure (5–45 atm) and is joined by a stream of hydrogen-rich recycle gas.
