沼氣提純主要目的是去除二氧化碳獲得高純度甲烷，沼氣提純技術(shù)多源于天然氣、合成氨變換氣的脫碳技術(shù)。由于沼氣的處理量遠小于天然氣或合成氨變換氣，在脫碳技術(shù)選擇上更注重小型化、節(jié)能化。
The main purpose of biogas purification is to remove carbon dioxide to obtain high-purity methane. Biogas purification technology is mostly derived from the decarbonization technology of natural gas and synthetic ammonia. As the treatment capacity of biogas is far less than that of natural gas or synthetic ammonia, more attention is paid to miniaturization and energy saving in the selection of decarbonization technology.
沼氣可提純制成生物天然氣，是可再生清潔能源。在沼氣行業(yè)內(nèi)部有一種生動的比喻，即建一口小型沼氣池，不僅相當于建了一座小型天然氣廠，還相當于建了一座小型污水處理廠、垃圾處理廠、有機肥料廠、小型林場。被群眾稱為“錢串子”“聚寶盆”，是一項投資小、作用大，利國利民的事業(yè)。
Biogas can be purified into bio natural gas, which is a renewable and clean energy. There is a vivid metaphor in the biogas industry, that is, to build a small biogas digester is not only equivalent to building a small natural gas plant, but also equivalent to building a small sewage treatment plant, garbage treatment plant, organic fertilizer plant and small forest farm. Known by the masses as "money strings" and "cornucopia", it is a cause with small investment, great role and benefits the country and the people.
沼氣還可治理大氣污染、江河污染。使用沼氣，室內(nèi)一氧化碳的濃度比燃煤降低80%，二氧化碳濃度降低60%，硫化氫降低80%，飄塵濃度降低90%，同時還大幅度降低飲用水源的細菌總數(shù)、大腸桿菌、氨氮等各項指標，保護了水源，改善了水環(huán)境質(zhì)量。
Biogas can also control air pollution and river pollution. Using biogas, the indoor carbon monoxide concentration is 80% lower than that of coal, the carbon dioxide concentration is 60%, the hydrogen sulfide concentration is 80% lower, and the floating dust concentration is 90%. At the same time, the total number of bacteria, E. coli, ammonia nitrogen and other indicators in the drinking water source are greatly reduced, which protects the water source and improves the water environment quality.
沼氣提純天然氣作為一種清潔的分布式能源，可替代石化天然氣，用于車用燃料、居民燃氣，是沼氣高值化、能源化利用的重要方式。我國不僅沼氣資源豐富，沼氣生產(chǎn)潛力巨大，未來生物質(zhì)能發(fā)展不可估量，當前沼氣的進一步利用開展的主要路線為發(fā)電和提純。迪爾空分可根據(jù)客戶不同的要求設(shè)計標準沼氣提純，沼氣提純設(shè)備環(huán)保、，實現(xiàn)經(jīng)濟效益與社會效益的雙贏。
As a clean distributed energy, purified natural gas from biogas can replace petrochemical natural gas for vehicle fuel and residential gas. It is an important way for high-value and energy utilization of biogas. China is not only rich in biogas resources, but also has great potential for biogas production. The future development of biomass energy is inestimable. At present, the main route for further utilization of biogas is power generation and purification. Deere air separation can design standard biogas purification according to different requirements of customers. The biogas purification equipment is environmentally friendly and can achieve win-win economic and social benefits.
