Natural Gas

Natural gas is a gas composed mainly by methane. Before it can be used as fuel it must undergo a process of purification in which other elements such as ethane, propane, butane, pentanes, and higher molecular weight hydrocarbons, elemental sulfur, carbon dioxide, water vapor, and sometimes helium and nitrogen are removed.

Natural gas is used in the generation of electricity generated by power plants; in homes for cooking and heating purposes; for transportation as an alternative to gasoline and diesel; in the production of ammonia for fertilizers; in the manufacture of plastics, paints, etc.

Natural Gas futures are traded on the NYMEX under ticker symbol NG in U.S dollars and cents per mmBtu.
