By performing a series of purification treatments such as desulfurization, decarbonization, and dehydration on biogas, clean and pollution-free natural gas can be produced, greatly increasing its combustion heat value. Decarburization tail gas can also produce liquid carbon dioxide, which can fully and effectively utilize biogas without generating secondary pollution.
According to the requirements of the final target product, using our company's technology, biogas can be converted into natural gas and directly transported to the natural gas pipeline network as civilian gas; Or CNG (compressed natural gas for vehicles) is made by compressing natural gas to 20~25MPa as vehicle fuel; The product gas can also be deeply cooled and liquefied to ultimately produce LNG (liquefied natural gas).

2、 Process Overview
沼氣制CNG的過程，其實就是一系列凈化過程及終升壓過程。
The process of producing CNG from biogas is actually a series of purification processes and the final boosting process.
1.硫含量過高則會腐蝕設備和管道，降低其使用壽命；
1. If the sulfur content is too high, it will corrode equipment and pipelines, reducing their service life;
2.CO2存在量越多則氣體熱值越低；
2. The more CO2 there is, the lower the calorific value of the gas;
3.水的存在會造成管道腐蝕，形成水合物限制或堵塞管線中氣體的流動，甚至會使燃燒器熄火；
3. The presence of water can cause pipeline corrosion, form hydrates to restrict or block the flow of gas in the pipeline, and even cause the burner to shut down;
4. As biogas is generated in an anaerobic environment, the O2 content generally does not exceed the standard, but it should be noted that the CNG standard requires that the O2 content after purification should not exceed 0.5%;
During the transportation of natural gas pipelines, water condenses into liquid at low temperatures, which reduces the cross-sectional area of the pipeline, increases the resistance and energy consumption during the transportation process, and even freezes and blocks the pipeline; The presence of external water can accelerate the corrosion of equipment by sulfides;
6.其它微量的N2、H2等在不影響天然氣標準要求的熱值時，可不予脫除。
6. Other trace amounts of N2, H2, etc. may not be removed when they do not affect the calorific value required by natural gas standards.
According to the analysis of relevant parameters and product requirements of raw material biogas, the raw material biogas can be sequentially subjected to processes such as desulfurization, pressurized drying, decarbonization, and CNG pressurization to obtain the product: compressed CNG for vehicles.
