As bio natural gas can be directly used as an alternative fuel for Petrochemical Natural gas, the development of biogas purification has become an important direction to increase the supply of natural gas.
Oil prices are rising, and many people are bemoaning the increasing cost of driving. The current biogas purification technology makes low-cost driving no longer a dream. This technology can not only make biogas directly replace gasoline as vehicle fuel, but also has better antiknock performance than gasoline.
Biogas for purification comes from a wide range of sources, mainly from biogas produced by anaerobic fermentation of organic waste and landfill gas produced by landfill. After dehydration, dust removal and desulfurization of biogas, CO2 in biogas can be effectively removed by physical or chemical methods, so that the methane content in biogas can be increased to more than 95%. The calorific value and the quality of impurity gas components meet the standards of natural gas and vehicle compressed natural gas. The purified natural gas can be used as vehicle gas, industrial gas or town gas.
There are many methods for biogas purification, including high pressure water washing, pressure swing adsorption (PSA), physical and chemical adsorption and membrane purification. The purification process varies according to the purification method, but the purpose is to remove carbon dioxide, hydrogen sulfide, steam and other gases, so as to increase the methane content in biogas, improve the combustion efficiency and reduce pollution.
Among these methods, some of them are highly mature in technology and equipment, and occupy a major share in the biogas purification market, such as high-pressure water washing method, PSA method and physicochemical adsorption method. At the same time, due to the research and application of new materials, membrane separation technology has become a new and popular method in biogas purification, which is an important development direction of biogas purification technology.
