Description
Technical field
The present invention relates to separation method and the system thereof of methane in a kind of mixed empty coal bed gas, belong to chemical technology field.
Background technology
Coal bed gas (CoalBedMethane, be called for short CBM), also known as coal mine gas or mine gas, results from coalification course, mainly composes with adsorbed state and is stored in coal seam, the unconventional gas resource of main component that to be a kind of with methane be.
At present, the major way of exploiting coal bed methane is ground drilling and down-hole extraction.In the exploitation of ground drilling technology coal bed gas abroad, Application comparison is many, and Chinese Geological situation is complicated, the gas permeability in major part coal seam is poor, by the restriction of technology and geological conditions, in the exploitation of China coal bed gas Application comparison many or down-hole extraction technology.In the coal bed gas adopting direct drilling technology to obtain, methane content is generally greater than 90%, form close with the natural gas of routine, directly can utilize the natural gas pretreating process processing purification of comparative maturity, then pass into gas distributing system after direct liquefaction accumulating or pressurization.The coal bed gas adopting extraction technology in down-hole to obtain generally all can be mixed into air, methane content lower (usual volume fraction is at 30%-80%), the down-hole extraction coal bed gas of seldom part is only had to obtain effective utilization at present, major part is directly entered in air, causes the very large wasting of resources and environmental pollution.
Many researchers have carried out large quantifier elimination to the separation of methane in mixed empty coal bed gas and recovery in recent years, and existing have low-temperature deep partition method, membrane separation process, pressure-variable adsorption partition method and hydrate separation method for separating of the method for methane in mixed empty coal bed gas.But said method but exists different defects, constrain the recovery of methane in mixed empty coal bed gas.
Low-temperature deep isolation technics utilizes the boiling point of each component in coal bed gas different, adopts the mode of cryogenic rectification and liquefaction by each Component seperation.This isolation technics requires to operate at about-150 DEG C, and energy consumption is higher, because containing oxygen in mixed empty coal bed gas, need first to carry out deoxidation, there is the danger of blast; Membrane separation technique realizes through the transfer rate of film is different under certain pressure reduction according to each component of gaseous mixture.But current developed membrane material is to the key component CH in coal bed gas
4and N
2separating effect not good, also there is the danger of blast simultaneously; PSA Technology utilize adsorbent under uniform temperature and pressure to gaseous mixture in the difference of each component adsorption capacity realize.Through the development of decades, pressure-variable adsorption is separated H
2, N
2and O
2worldwide all generally use etc. technology, but also do not use pressure-variable adsorption partition method to be separated the example of the commercial Application of mixed empty coal bed gas at present at home.
The all unrealized industrialized main cause of above-mentioned three kinds of isolation technics is that mixed empty coal bed gas is very easily exploded, and can not ensure the safety of separation process.Hydrate separation method is a kind of isolation technics of separation low boiling mist newly, and principle is the complexity forming hydrate according to gas with various, thus realizes the separation of each component in mist.Existing hydrate separation method can make mixed empty coal bed gas be separated in water saturated environment under carry out, but because the separation of hydrate needs to carry out under pressure, early stage the same danger that there is blast in compression boost process is implemented to mixed empty coal bed gas and be difficult to equally adopt.
