  由于生物天然气可以直接作为石化天然气的替代燃料,所以发展沼气提纯已成为增加天然气供应量的一个重要方向。
  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.
  油价节节攀升,很多人都在感叹开车的成本越来越高。目前使用的沼气提纯技术让低成本开车不再成为梦想。这一技术不但可以让沼气直接取代汽油作为车用燃料,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.

  提纯用的沼气,来源广泛,主要来源于有机废弃物厌氧发酵产生的沼气和垃圾填埋场产生的填埋气。沼气经过脱水、除尘和脱硫后,通过物理或化学方法有效地去除沼气中的CO2,使得沼气中甲烷的含量提高到95%以上,热值和杂质气体组分品质符合天然气标准和车用压缩天然气的标准。提纯后的天然气可用于车用燃气、工业燃气或城镇燃气等。
  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.
  进行沼气纯化的方法有很多,主要有包括高压水洗、变压吸附(PSA)、物理化学吸附以及膜提纯等几种。提纯过程根据提纯的方法各有不同,但目的都是为了去除二氧化碳,硫化氢,水蒸气等气体,使沼气中的甲烷含量升高,提高燃烧效率并减少污染。
  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.
  这些方法中,有些其技术和设备的成熟度高,在沼气提纯市场占据主要份额,如高压水洗法,PSA法以及物理化学吸附法。同时,由于新材料的研究与应用,使得膜分离技术也成为沼气提纯中的一种新兴和热门的方法,是沼气提纯技术中的一个重要发展方向。
  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.
