Coal bed-methane is adhered to coal base, partially free from coal pore or dissolved in the water contained in coal bed. It is of non-conventional natural gas, and associated with coal exploration.
When coal-bed methane is from ground coal bed, it mainly contains the most majority of methane (above 90% CH4). The process of purification and liquefaction of coal-bed methane is the same as those for conventional natural gas.
When methane gas is from underground coal pit, it mainly contains methane (CH4), N2, O2 and other impurities. As contents of O2 is relatively high (about 10%), explosion can easily take place. Therefore, it is first step to remove O2 out of methane gas, and then the process of purification and liquefaction of it is the same as those for conventional natural gas.
