Natural gas Some of these gases include heptane, pentane, propane and other hydrocarbons with molecular weights above methane (). The natural gas transmission lines extend to the natural gas processing plant or unit which removes the higher molecular weighted hydrocarbons to produce natural gas with energy content between . The processed natural gas may then be used for residential, commercial and industrial uses. Natural gas flowing in the distribution lines is called mid-stream natural gas and is often used to power engines which rotate compressors. These compressors are required in the transmission line to pressurize and re-pressurize the mid-stream natural gas as
Natural gas in the United States price of natural gas has been relatively cheap on the North American market, especially compared to oil. Electricity from oil-powered generators in the US declined 81 percent from 2005 to 2014. The states which use the most natural gas for electricity production are, in descending order, Texas, Florida, California, and New York. Liquefied petroleum gas includes the butane and propane natural gas liquids removed in gas processing. They are sold for home heating, cooking, and increasingly for motor fuel. The industry segment is represented by the National Propane Gas Association. Natural gas, in the forms of compressed natural gas, liquified
