摘　　要：厌氧消化产生的沼气主要成分是CH_(4)和CO_(2)。沼气提纯是利用特定的分离技术,将CO_(2)从沼气中分离出去,从而得到高纯度的生物天然气。生物天然气可以作为石化天然气的替代燃料,是一种可持续有价值的能量来源。文章介绍了沼气提纯的基本概念,综述了主流的沼气提纯工艺的技术特点,比较了提纯方法的技术参数和优劣势,并分析了我国天然气产业的发展前景。The main components of biogas produced by anaerobic digestion are CH_(4) and CO_(2).Biogas upgrading technology is to separate carbon dioxide from biogas by specific separation technology to obtain high-purity biological natural gas.Biogas can be used as an alternative fuel for petrochemical natural gas,and it is a sustainable and valuable energy source.This paper introduced the basic concept of biogas purification,summarized the technical characteristics of the mainstream biogas purification process,compared the technical parameters and advantages and disadvantages of different purification methods,and analyzed the development prospect of domestic natural gas industry.
