　　由于生物天然气可以直接用作石化天然气的替代燃料，因此沼气净化技术的发展已成为增加天然气供应的重要方向。此外，石油价格上涨，许多人都为不断增加的驾驶成本而感叹。目前，沼气脱硫净化技术使得低成本驾驶不再是梦想。该技术不仅可以使沼气直接替代汽油作为车用燃料，而且具有比汽油更好的抗爆性能，沼气提纯可以有效地增加能源供应。

　　As bio natural gas can be directly used as an alternative fuel for Petrochemical Natural gas, the development of biogas purification technology has become an important direction to increase the supply of natural gas. In addition, oil prices have risen, and many people are bemoaning the increasing driving costs. At present, biogas desulfurization and 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 purification can effectively increase energy supply.

　　用于净化的沼气来源广泛，主要来自有机废物厌氧发酵产生的沼气和垃圾填埋场产生的垃圾填埋气。沼气经过脱水，除尘，脱硫后，可通过物理或化学方法有效去除沼气中的CO2，使沼气中甲烷含量提高到95%以上。杂质气体的热值和质量符合天然气和车辆压缩天然气的标准。纯化的天然气可以用作车用气体，工业用气体或城市用气体。

　　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, CO2 in biogas can be effectively removed by physical or chemical methods, and the methane content in biogas can be increased to more than 95%. The calorific value and quality of impurity gas meet the standards of natural gas and vehicle compressed natural gas. Purified natural gas can be used as vehicle gas, industrial gas or city gas.
生物脱硫

　　沼气提纯方法很多，包括高压水洗，变压吸附(PSA)，物理和化学吸附以及膜净化。净化过程因净化方法而异，但目的是去除二氧化碳，硫化氢，蒸汽等气体，以增加沼气中的甲烷含量，提高燃烧效率，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 with 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 combustion efficiency and reduce pollution.

　　在这些方法中，其中一些在技术和设备上已经非常成熟，并且在沼气提纯市场上占有主要份额，例如高压水洗方法，PSA方法和理化吸附方法。同时，由于新材料的研究和应用，膜分离技术已成为沼气脱硫净化的一种新的，流行的方法，这是沼气脱硫净化技术的重要发展方向。

　　Among these methods, some of them are very 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 physical and chemical 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 for biogas desulfurization and purification, which is an important development direction of biogas desulfurization and purification technology.
