Natural gas mains are made from a variety of materials: historically cast iron, though more modern mains are made from steel or polyethylene. In some states in the USA natural gas can be supplied by independent natural gas wholesalers/suppliers using existing pipeline owners' infrastructure through Natural Gas Choice programs.
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 heating value depends on the source of gas that is used and the process that is used to liquefy the gas. The range of heating value can span ±10 to 15 percent. A typical value of the higher heating value of LNG is approximately 50 MJ/kg or 21,500 BTU/lb. [2] A typical value of the lower heating value of LNG is 45 MJ/kg or 19,350 BTU/lb.
Substitute natural gas (SNG), or synthetic natural gas, is a fuel gas (predominantly methane, CH 4) that can be produced from fossil fuels such as lignite coal, oil shale, or from biofuels (when it is named bio-SNG) or using electricity with power-to-gas systems.
GTL is a mechanism to bring down the diesel/gasoline/crude oil international prices at par with the natural gas price in an expanding global natural gas production at cheaper than crude oil price. When natural gas is converted in to GTL, the liquid products are easier to export at cheaper price rather than converting in to LNG and further ...
Although a few of its products are now made overseas — and Lasko motors come from China — the company continues to make many American-made products at plants in Tennessee, Texas, and ...
Although natural gas used for vehicle fuel increased 60 percent in the decade 2004-2014, in 2014 it still made up only 3.7 percent on a BTU-basis of fossil fuel use (gasoline, diesel, and natural gas) as transportation fuel in the US. [36] Transportation fuel made up 0.13 percent of natural gas consumption in 2014.
Drip gas, so named because it can be drawn off the bottom of small chambers (called drips) sometimes installed in pipelines from gas wells, is another name for natural-gas condensate, a naturally occurring form of gasoline obtained as a byproduct of natural gas extraction. It is also known as "condensate", "natural gasoline", "casing head gas ...
