Crude oil wells: Natural gas that comes from crude oil wells is typically called associated gas. This gas could exist as a separate gas cap above the crude oil in the underground reservoir or could be dissolved in the crude oil, ultimately coming out of solution as the pressure is reduced during production.
A natural-gas processing plant in Aderklaa, Austria. Natural-gas processing is a range of industrial processes designed to purify raw natural gas by removing contaminants such as solids, water, carbon dioxide (CO 2), hydrogen sulfide (H 2 S), mercury and higher molecular mass hydrocarbons to produce pipeline quality dry natural gas [1] for pipeline distribution and final use.

The Mossmorran Natural Gas Liquids (NGL) plant is part of the northern North Sea Brent oil and gas field system and is located on the outskirts of Cowdenbeath, Scotland. The Mossmorran facilities comprise two plants: the Fife NGL Plant operated by Shell and the Fife Ethylene Plant operated by ExxonMobil. An associated sea-going tanker loading ...
Fractionation is also used for culinary purposes, as coconut oil, palm oil, and palm kernel oil are fractionated to produce oils of different viscosities, that may be used for different purposes. These oils typically use fractional crystallization (separation by solubility at temperatures) for the separation process instead of distillation.
Naphtha (/ ˈ n æ f θ ə /, recorded as less common or nonstandard [1] in all dictionaries: / ˈ n æ p θ ə /) is a flammable liquid hydrocarbon mixture.Generally, it is a fraction of crude oil, but it can also be produced from natural-gas condensates, petroleum distillates, and the fractional distillation of coal tar and peat.
NGL is first pumped as liquid to this pressure. A series of heat exchangers are used to regasify the LNG. These may include submerged combustion vaporisers, [ 15 ] or an intermediate fluid exchanger (using propane or other fluids), [ 16 ] or the use of waste heat from a nearby plant such as a power station. [ 17 ]
Most modern wells are planned to include gas pipeline transport, but some oil wells are drilled only to get the more lucrative oil, in which case the options are to locally use, process, or dispose of the APG. A traditional local use is to re-inject the gas for storage, and to re-pressurize the well to extend the oil production lifetime.
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.
