About Natural Gas

Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but most commonly includes varying amounts of other higher alkanes and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas.

Natural gas was created over time by two mechanisms: biogenic and thermogenic. Biogenic gas is created by methanogenic organisms in marshes, bogs, landfills and shallow sediments. Deeper in the earth, at greater temperature and pressure, thermogenic gas is created from the buried organic material.

Before natural gas can be used as a fuel, most, but not all, must be processed to remove impurities, including water to meet the specifications of marketable natural gas. The by-products of this processing include ethane, propane, butanes, pentanes, and higher molecular weight hydrocarbons, hydrogen sulfide (which may be converted into pure sulfur), carbon dioxide, water vapor and sometimes helium/nitrogen.


Why you should switch to Natural Gas

  • Natural Gas is transported through pipelines to the end user, which is a very efficient, safe and reliable method of transporting natural gas. This eliminates the need for storing the gas in cylinders.
  • It is better for the environment as it burns completely and produces lower levels of carbon, which keeps the air clean.
  • It is less expensive compared to other energy sources.
  • Natural gas is lighter than air, so it disperses in the environment easily and reduces the risk of an accident.
  • Natural Gas produces more energy when burned, compared to other gases like propane.
