沼气提纯有什么意义?

沼气提纯就是去除沼气中的杂质组分,使之成为甲烷含量高、热值和杂质气体组分品质符合天然气标准要求的高品质CH4。

Biogas purification is to remove the impurity components in biogas and make it high-quality CH4 with high methane content, calorific value and impurity gas component quality meeting the requirements of natural gas standards.
厌氧过程产生的沼气中含有约55%的CH4和45%的CO2,还有少量的H2S、H2O等气体成分,通过分离提纯可将CH4浓度提高到95%以上。沼气分离提纯系统分为预处理和膜分离两部分。
The biogas produced by anaerobic process contains about 55% CH4 and 45% CO2, as well as a small amount of H2S, H2O and other gas components. The concentration of CH4 can be increased to more than 95% through separation and purification. The biogas separation and purification system is divided into two parts: pretreatment and membrane separation.

提纯的意义,沼气中甲烷的含量只有60%左右,其余为二氧化碳、氮气、硫化氢等,经过提纯,可使甲烷含量达到97%以上,达到城市天然气的标准。甲烷燃烧产生CO2量为汽油的60%,且不排放硫化物和氮化物等形成酸雨的大气污染气体,实现了环保效应。生物天然气的一大优势,是可以完全替代车用汽油、柴油,乃至替代车用化石天然气;并能充分利用现成的天然气储、运、加气的基础设施,从而大幅节省开发应用的投资,市场前景广阔。
The significance of purification: the methane content in biogas is only about 60%, and the rest is carbon dioxide, nitrogen and hydrogen sulfide. After purification, the methane content can reach more than 97%, reaching the standard of urban natural gas. The amount of CO2 produced by methane combustion is 60% of that of gasoline, and does not emit atmospheric pollutants such as sulfide and nitride to form acid rain, realizing the effect of environmental protection. A major advantage of biological natural gas is that it can completely replace vehicle gasoline, diesel, and even replace vehicle fossil natural gas; It can make full use of the existing infrastructure of natural gas storage, transportation and filling, so as to greatly save the investment in development and application, and the market prospect is broad.
