鉴于全球化石燃料所面临的枯竭危机，对生物质燃料的开发和应用已经成为各国关注的重点。其中，沼气和生物天然气作为可再生能源，具有利用成本低、对环境无污染的特点，是替代常规化石能源的优质环保燃料。随着大型沼气、生物天然气工程的快速发展，沼气脱硫提纯为高附加值生物燃气的需求日益迫切，沼气净化提纯技术得到了不同程度的应用和发展。
In view of the global exhaustion crisis of fossil fuels, the development and application of biomass fuels has become the focus of attention of all countries. Among them, biogas and biogas, as renewable energy sources, have the characteristics of low cost and no pollution to the environment. They are high-quality environmental protection fuels instead of conventional fossil energy. With the rapid development of large-scale biogas and biogas projects, the demand of biogas desulfurization and purification for high value-added biogas is increasingly urgent, and the technology of biogas purification and purification has been applied and developed to varying degrees.
通过去除沼气中的杂质，来对沼气进行净化提纯，提纯后的甲烷气体浓度和燃烧热值，即可替代天然气用作城市管道燃气或者用作车用燃气，能够节约和替代大量化石能源，减少污染物和温室气体排放，大大提高了沼气工程的经济效益和沼气的深度利用。
By removing the impurities in biogas, the biogas can be purified and purified. The purified methane gas concentration and combustion calorific value can replace natural gas for urban pipeline gas or vehicle gas. It can save and replace a large number of fossil energy, reduce pollutants and greenhouse gas emissions, and greatly improve the economic benefits of biogas engineering and the deep utilization of biogas.
