 Natural Gas is a naturally-occurring
mixture of hydrocarbon and non-hydrocarbon gases found in porous formations
beneath the earth's surface. It is
not a pure element like oxygen, but a mixture of gases of which hydrocarbon
gases are the components that are combustible and produce heat.
Natural gas
distributed by utilities varies in composition. The heat-producing hydrocarbons are
composed of the elements Carbon and Hydrogen. Methane (CH4) is always the largest component. Ethane, propane (C3H8) and butane are heavier, "hotter" hydrocarbons produced from natural gas
wells, and are present in low concentration. Nitrogen, Oxygen, and Carbon Dioxide are
the major components (99.9%) of air, but are considered contaminants of natural
gas.
What is Natural Gas?
Read a detailed article from the American Gas Association, the premier organization for gas utilities and pipelines. What is Natural Gas?
Properties of natural gas.
Natural gas properties are detailed on the Questar website. This company operates gas wells and gas gathering pipelines in southwest Wyoming, one of which delivers gas to PNG near Pinedale. Properties of Natural Gas
Combustion of natural gas is the
chemical reaction of oxygen with a combustible material which produces
heat.
There are three
requirements for combustion. If one
of these three components is missing, combustion cannot occur.
- Fuel (natural gas, in this case).
- Oxygen.
- A source of ignition.
Natural gas will not
burn unless the mixture is within a flammable range of roughly 5 to 15% gas in
air. The most efficient or ideal
mixture is about 10% gas.
A combustible
mixture of natural gas in air will not ignite until its temperature is raised to
the minimum ignition temperature, which is 1150°F. Here are possible sources of
ignition:
- Any open flame such as a pilot light, match, or lighted candle.
- Static electricity spark.
- Light switch.
- Heating element or motor in an electric appliance.
- Internal combustion engine, while running or starting.
- Overhead electrical transformer.
- A ringing doorbell.
