Natural gas is a mixture ofcobustible gases formed underground by decomposition of organic materials in plant and animal. It is ussually found in areas where oil is present, although there are several large underground resevoirs of natural gas where there is little or no oil.
Natural gas is extracted from well, without any refining, but most requires processing. In other case, we can also generate methane from coal deposit, known as Coal Bed Methane (CBM) or derived from biologocal waste, known as biogas.
Transport System For Natural Gas
Most common means to transport natural gas is in its matural gaseous state by pipeline, after liquefaction by colling by tankers as liquefied Natural Gas (LNG) or after compression as Compressed Natural Gas (CNG).
