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 Act of 1938 In 1938, the Natural Gas Act gave FPC jurisdiction over interstate natural gas pipelines and wholesale sales. In 1938, the Natural Gas Act gave FPC jurisdiction over interstate natural gas pipelines and wholesale sales. In 1942, this jurisdiction was expanded to cover the licensing of more natural gas facilities. In 1954, the Supreme Court decision in "Phillips v. Wisconsin" extended FPC jurisdiction over all wellhead sales of natural gas in interstate commerce. Congress passed the U.S. Department of Energy Organization Act in 1977, which consolidated various energy-related agencies into a Department of Energy. Congress insisted that a separate independent regulatory
