由于生物天然氣可以直接作為石化天然氣的替代燃料，所以發(fā)展沼氣提純已成為增加天然氣供應量的一個重要方向。
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.
油價節(jié)節(jié)攀升，很多人都在感嘆開車的成本越來越高。目前使用的沼氣提純技術(shù)讓低成本開車不再成為夢想。這一技術(shù)不但可以讓沼氣直接取代汽油作為車用燃料，抗爆性也比汽油更好。
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.
提純用的沼氣，來源廣泛，主要來源于有機廢棄物厭氧發(fā)酵產(chǎn)生的沼氣和垃圾填埋場產(chǎn)生的填埋氣。沼氣經(jīng)過脫水、除塵和脫硫后，通過物理或化學方法有效地去除沼氣中的CO2，使得沼氣中甲烷的含量提高到95％以上，熱值和雜質(zhì)氣體組分品質(zhì)符合天然氣標準和車用壓縮天然氣的標準。提純后的天然氣可用于車用燃氣、工業(yè)燃氣或城鎮(zhèn)燃氣等。
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.
進行沼氣純化的方法有很多，主要有包括高壓水洗、變壓吸附（PSA）、物理化學吸附以及膜提純等幾種。提純過程根據(jù)提純的方法各有不同，但目的都是為了去除二氧化碳，硫化氫，水蒸氣等氣體，使沼氣中的甲烷含量升高，提高燃燒效率并減少污染。
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.
這些方法中，有些其技術(shù)和設(shè)備的成熟度高，在沼氣提純市場占據(jù)主要份額，如高壓水洗法，PSA法以及物理化學吸附法。同時，由于新材料的研究與應用，使得膜分離技術(shù)也成為沼氣提純中的一種新興和熱門的方法，是沼氣提純技術(shù)中的一個重要發(fā)展方向。
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.
