Biogas can be produced by anaerobic treatment of wastes containing a large amount of organic wastes, such as livestock and poultry wastes, sludge from municipal sewage treatment, municipal domestic waste and kitchen waste. Biogas is a kind of combustible gas produced by specific microorganisms degrading organic matter under anaerobic conditions. At present, the technologies widely used in the utilization of biogas resources are mainly the purification of biogas to produce natural gas and the generation of electricity by biogas. In this paper, the process of biogas purification of natural gas is analyzed, hoping to be helpful to everyone!

利用沼气提纯天然气，需作以下处理：

Purification of natural gas by biogas requires the following treatment:

1、 水分去除：避免水分在设备气体管路中聚焦，和硫化氢结合会产生腐蚀性的酸溶液，引起腐蚀。由上表的沼气成分分析可知，利用沼气生产天然气，需作以下处理：

1. Moisture removal: Avoid focusing water in equipment gas pipeline, and hydrogen sulfide will produce corrosive acid solution, causing corrosion. According to the analysis of the biogas composition on the upper surface, the following treatment is needed for the production of natural gas from biogas:

2、 硫化氢去除：硫化氢具有毒性、腐蚀性，会腐蚀设备，且燃烧时生成二氧化硫造成污染，因此必须降低硫化氢浓度，直至满足生产设备及国家相关规范对二氧化硫排放限值的要求。

2. Removal of hydrogen sulfide: hydrogen sulfide is toxic and corrosive, which will corrode equipment and cause pollution by sulfur dioxide generated during combustion. Therefore, the concentration of hydrogen sulfide must be reduced until it meets the requirements of production equipment and relevant national standards for sulfur dioxide emission limits.

3、 二氧化碳去除：提高沼气的热值。

3. Carbon dioxide removal: increase the calorific value of biogas.

沼气提纯制取天然气，需采用脱硫、脱碳工艺，降低沼气中的H2S和CO2含量，提高CH4含量，提纯后的沼气含CH490%以上，成分与天然气近似，可以作为天然气使用。此外，yl6809永利制天然气方式投资较小，且经济效益较好，值得被广泛推广使用。

In order to purify natural gas from biogas, desulfurization and decarbonization processes should be adopted to reduce the content of H2S and CO2 in biogas and increase the content of CH4. The purified biogas contains more than 490% CH4, and its composition is similar to that of natural gas, so it can be used as natural gas. In addition, the way of biogas purification to produce natural gas has less investment and better economic benefits, which is worthy of being widely used.
