Natural gas is a naturally occurring hydrocarbon gas mixture comprising substantially varying amounts of other higher alkanes and sometimes a small amount of carbon dioxide, nitrogen, hydrogen sulfide or helium. It occurs when layers of decomposing plant and animal material are exposed to intense heat and pressure on Earth’s surface for millions of years. The energy of plants initially obtained from the sun is stored in the form of chemical bonds in the gas.
Natural gas is a naturally occurring hydrocarbon used as an energy source for heating, cooking and electricity production. It is used as a fuel for vehicles in the production of plastics and other commercially important organic chemicals as well as chemical raw materials. Natural gas is called non-renewable source.
Natural gas is found in deep underground rock formations or associated with other hydrocarbon reservoirs such as coal deposits and methane clathrates. Oil is another source and fossil fuel near and near natural gas. Natural gas is often produced by two mechanisms: biogenic and thermogenic. Biogenic gas is produced by methanogenic organisms in marshes, marshes, dumps and shallow deposits. In the soil, thermogenic gas is formed from the organic material embedded in the deeper, higher temperature and pressure.
In the oil production, the gas usually burns as a flame gas. The World Bank estimates that 150 m3 of natural gas is exploded or aired annually. Before being used as a natural gas fuel, most, but not all, should be processed to remove foreign substances, including water, to meet the characteristics of marketable natural gas. By-products of this process are: ethane, propane, butanes, pentanes and higher molecular weight hydrocarbons, hydrogen sulfide (convertible to pure sulfur), carbon dioxide, water vapor, and sometimes helium and nitrogen.
Natural gas is called “gas”, especially when compared to other sources of energy, such as oil or coal. However, gasoline, in particular gasoline, should not be confused in North America, where the gas is often shortened in color use.
