沼气提纯主要目的是去除二氧化碳获得高纯度甲烷,沼气提纯技术多源于天然气、合成氨变换气的脱碳技术。由于沼气的处理量远小于天然气或合成氨变换气,在脱碳技术选择上更注重小型化、节能化。
The main purpose of biogas purification is to remove carbon dioxide and obtain high-purity methane. Biogas purification technology mostly comes from the decarbonization technology of natural gas and synthetic ammonia. Because 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.
沼气可提纯制成生物天然气,是可再生清洁能源。在沼气行业内部有一种生动的比喻,即建一口小型沼气池,不仅相当于建了一座小型天然气厂,还相当于建了一座小型污水处理厂、垃圾处理厂、有机肥料厂、小型林场。被群众称为“钱串子”“聚宝盆”,是一项投资小、作用大,利国利民的事业。
Biogas can be purified into biological natural gas, which is a renewable and clean energy. There is a vivid metaphor within the biogas industry, that is, building a small biogas digester is equivalent to building not only a small natural gas plant, but also 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.
沼气还可治理大气污染、江河污染。使用沼气,室内一氧化碳的浓度比燃煤降低80%,二氧化碳浓度降低60%,硫化氢降低80%,飘尘浓度降低90%,同时还大幅度降低饮用水源的细菌总数、大肠杆菌、氨氮等各项指标,保护了水源,改善了水环境质量。
Biogas can also control air pollution and river pollution. Using biogas, the indoor concentration of carbon monoxide is 80% lower than that of coal, the concentration of carbon dioxide is 60%, the concentration of hydrogen sulfide is 80% lower, and the concentration of floating dust is 90%. At the same time, it also greatly reduces the total number of bacteria, Escherichia coli, ammonia nitrogen and other indicators of drinking water source, protects the water source and improves the quality of water environment.
沼气提纯天然气作为一种清洁的分布式能源,可替代石化天然气,用于车用燃料、居民燃气,是沼气高值化、能源化利用的重要方式。我国不仅沼气资源丰富,沼气生产潜力巨大,未来生物质能发展不可估量,当前沼气的进一步利用开展的主要路线为发电和提纯。迪尔空分可根据客户不同的要求设计标准沼气提纯,沼气提纯设备环保、高能,实现经济效益与社会效益的双赢。
As a clean distributed energy, biogas purified natural gas can replace petrochemical natural gas for vehicle fuel and residential gas. It is an important way of 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 immeasurable. At present, the main route for the further utilization of biogas is power generation and purification. Deere air separation can design standard biogas purification according to different requirements of customers. Biogas purification equipment is environmentally friendly and high-energy, so as to achieve win-win economic and social benefits.
