通過對沼氣進行脫硫、脫碳、脫水等一系列凈化處理，即可制得清潔無污染的天然氣，使其燃燒熱值大幅提升。脫碳尾氣還可以制取液體二氧化碳，從而可以將沼氣進行充分有效的利用，且不會產(chǎn)生二次污染。
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.
根據(jù)終目標產(chǎn)品的要求，采用本公司技術(shù)，可將沼氣制得天然氣，直接輸送至天然氣管網(wǎng)作為民用燃氣；或通過將天然氣壓縮至20～25MPa制得CNG（車用壓縮天然氣）作為車用燃料；也可以將產(chǎn)品氣深冷液化并終制得LNG(液化天然氣)。
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).

二、工藝概述
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(shè)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?xí)谷紵飨ɑ穑?/div>
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.由于沼氣通過是在厭氧環(huán)境下產(chǎn)生的，O2含量一般不會超標，但需注意CNG標準中要求凈化后O2含量不得高于0.5%；
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%;
5.在天然氣管道輸送過程中，水分在低溫下冷凝成液體，會減少管道截面積，增加輸送過程阻力和能耗，甚至結(jié)冰堵塞管道；另外水的存在會加速硫化物對設(shè)備的腐蝕；
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.
根據(jù)原料沼氣相關(guān)參數(shù)及產(chǎn)品要求分析，原料沼氣可依次進行脫硫、加壓干燥、脫碳、CNG增壓等工序，即可獲得產(chǎn)品：車用壓縮CNG。
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.
