The main component of CNG (Compressed Natural Gas) is CH4-methane (accounting for 85%–95%), taken from natural gas field, associated petroleum gas in the process of oil field exploitation which is compressed at high pressure (200 to 250 bar) into specialized tanks to be transported to the point of consumption.
