生物天然氣是以農(nóng)作物秸稈、畜禽糞污、餐廚垃圾、農(nóng)副產(chǎn)品加工廢水等各類城鄉(xiāng)有機(jī)廢棄物為原料，經(jīng)厭氧發(fā)酵和凈化提純產(chǎn)生的綠色低碳清潔可再生的天然氣，同時(shí)厭氧發(fā)酵過程中產(chǎn)生的沼渣沼液可生產(chǎn)有機(jī)肥。
Biological natural gas is a green, low-carbon, clean and renewable natural gas produced by anaerobic fermentation, purification and purification with various urban and rural organic wastes such as crop straw, livestock and poultry manure, kitchen waste and agricultural and sideline product processing wastewater as raw materials. At the same time, the biogas residue and biogas liquid produced in the process of anaerobic fermentation can produce organic fertilizer.
沼氣的主要成分是CH4和CO2，將CO2從混合氣中分離得到的高純度甲烷氣被稱為生物天然氣。生物天然氣可以直接作為石化天然氣的替代燃料，發(fā)展沼氣已成為增加天然氣供應(yīng)量的一個(gè)重要方向。人類對(duì)天然氣需求量的增加推動(dòng)了生物天然氣技術(shù)的發(fā)展。沼氣提純生物天然氣可高值化利用沼氣，有效減少沼氣工程因沼氣利用不充分而排空造成的溫室效應(yīng)，具有環(huán)保和能源雙重效益。。
The main components of biogas are CH4 and CO2. The high-purity methane gas obtained by separating CO2 from the mixture is called biological natural gas. Biogas can be directly used as an alternative fuel for Petrochemical Natural gas. The development of biogas has become an important direction to increase the supply of natural gas. The increase of human demand for natural gas promotes the development of biological natural gas technology. Biogas purification of biological natural gas can make high-value use of biogas, effectively reduce the greenhouse effect caused by the emptying of biogas project due to insufficient utilization of biogas, and has the dual benefits of environmental protection and energy..

Four new anaerobic fermentation units, straw storage shed, pump house, double membrane gas storage tank, natural gas compression plant, CNG filling station building, organic fertilizer processing, biogas residue and biogas liquid temporary storage tank, wastewater treatment tank and other projects are to be built, and 92 sets of straw chopper, grass grabber, loader, solid feeding system, pneumatic conveying tank, biogas liquid circulating tank and other instruments and equipment are to be purchased.
規(guī)模化生物天然氣試點(diǎn)項(xiàng)目充分利用了秸稈等農(nóng)業(yè)生產(chǎn)剩余物，實(shí)現(xiàn)了廢棄資源的多層次循環(huán)利用，對(duì)于發(fā)展生態(tài)循環(huán)農(nóng)業(yè)有著重要的意義。項(xiàng)目有利于擴(kuò)大農(nóng)民就業(yè)、增加農(nóng)民收入，而且還能保護(hù)生態(tài)環(huán)境、改善居民生活條件，經(jīng)濟(jì)效益、生態(tài)效益和社會(huì)效益十分明顯。
The large-scale bio natural gas pilot project makes full use of agricultural production residues such as straw and realizes the multi-level recycling of waste resources, which is of great significance for the development of ecological circular agriculture. The project not only helps to expand farmers' employment and increase farmers' income, but also protects the ecological environment and improves residents' living conditions. The economic, ecological and social benefits are very obvious.
解決方案
Solution
該項(xiàng)目需要對(duì)天然氣提純前后的甲烷CH4、二氧化碳CO2、硫化氫H2S氣體含量進(jìn)行實(shí)時(shí)在線監(jiān)測(cè)，從而調(diào)整相應(yīng)的工藝，提高天然氣提純的純度，增加產(chǎn)業(yè)效益。
The project requires real-time online monitoring of methane CH4, carbon dioxide CO2, hydrogen sulfide and H2S before and after natural gas purification, so as to adjust the corresponding process, improve the purity of natural gas purification and increase industrial benefits.
