Methane (swamp gas, CH4) is a natural combustible gas located in the sedimentary cover of the Earth crust in the form of free accumulations (deposits), in solution (oil, formation and surface waters), dispersed, sorbed (rocks and organic material) and in solid (gas hydrate) phases.

  • Specific gravity of methane: 0.555 (20°С);
  • Molecular mass: 16.04;
  • Melting point: −182°С;
  • Critical pressure: 4.58 MPa;
  • Critical temperature: −82.4°С;
  • Flash point: −187.8°С;
  • Autoignition temperature: 537.8°С.

  • What is associated petroleum gas

    Associated petroleum gas (APG) is gas dissolved in oil. Associated petroleum gas is produced in the process of oil production, so it is actually a derivative. But APG itself is also a valuable raw material for further processing.

  • What is natural gas

    Natural gas is a mixture of hydrocarbons, a subject of a religious cult and academic disputes, as well as an essential resource. It is invisible and odorless. The amount of natural gas in Russia is more than wherever in the world.

  • How to produce gas from coal beds

    Methane should be extracted from mines to prevent explosions. The United States was the first country that decided to turn it into a commercial enterprise. Ten per cent of gas is produced there using this technique. Production from coal beds is promising in Russia as well.

  • What can be manufactured from natural gas

    Natural gas burns very well. Therefore, it is mostly used for generating electric or thermal energy. However, it can also be used to make fertilizers, fuel, paint, and many other items.
