Compressed Natural Gas

Compressed Natural Gas, in short CNG is nothing but Natural gas compressed for the use of transport sector. Due to its low density, it is compressed to a pressure of 200-250 kg/sq. cm to enhance the vehicle on-board storage capacity. Principal constituents of natural gas are Methane and Ethane, but most gases contain varying amounts of heavier hydrocarbons that are normally removed by processing. After recovery of the heavier hydrocarbons, the remaining gas, known as lean gas, is returned to the pipeline system. Natural gas is drawn from pipeline system for compression and distribution as CNG. Predominantly Methane is available in the lean gas, hence CNG contains mostly methane (normally not less than 85%).
