近年來人們對能源的重視度日益提高,沼氣作為一種清潔能源受到社會各界的關(guān)注,沼氣的利用能夠使資源得到優(yōu)化利用,與我國可持續(xù)發(fā)展戰(zhàn)略契合。結(jié)合實(shí)際狀況來看,在沼氣的利用中提純能夠使沼氣限度被利用。
In recent years, people pay more and more attention to energy. As a clean energy, biogas has attracted the attention of all sectors of society. The utilization of biogas can optimize the utilization of resources, which is in line with China's sustainable development strategy. Combined with the actual situation, the purification of biogas in the utilization of biogas can make the limited utilization of biogas.
生物天然氣是沼氣通過凈化提純后得到的綠色、低碳、清潔環(huán)保的可再生燃?xì)?與常規(guī)天然氣成分、熱值等基本一致。它的使用為傳統(tǒng)沼氣產(chǎn)業(yè)開辟了新的應(yīng)用領(lǐng)域,提高了傳統(tǒng)沼氣工程的經(jīng)濟(jì)性,促進(jìn)了沼氣工程運(yùn)營的持續(xù)性和穩(wěn)定性,以及人類對天然氣需求量的增加推動了沼氣提純制天然氣的發(fā)展,使得沼氣提純制天然氣這一技術(shù)具有廣闊的市場前景。
Biological natural gas is a green, low-carbon, clean and environment-friendly renewable gas obtained by purification and purification of biogas, which is basically consistent with the composition and calorific value of conventional natural gas. Its use has opened up new application fields for the traditional biogas industry, improved the economy of the traditional biogas project, promoted the sustainability and stability of the operation of the biogas project, and the increase of human demand for natural gas has promoted the development of biogas purification to natural gas, making the technology of biogas purification to natural gas have broad market prospects.
沼氣主要成分為甲烷和二氧化碳,還含有少量的水、硫化氫、有機(jī)硫、氧氣、氮?dú)獾入s質(zhì),通過對沼氣進(jìn)行凈化提純,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,可制取高品質(zhì)的生物天然氣,可以直接作為石化天然氣的替代燃料。由于沼氣是一種清潔再生能源,用處普遍,價錢低廉,容易獲取等優(yōu)勢,現(xiàn)已替代天然氣的使用。
Biogas is mainly composed of methane and carbon dioxide, and also contains a small amount of water, hydrogen sulfide, organic sulfur, oxygen, nitrogen and other impurities. Through the purification and purification of biogas, the high-purity methane gas obtained by separating CO2 from the mixture is called biological natural gas, which can produce high-quality biological natural gas and can be directly used as an alternative fuel for Petrochemical Natural gas. Because biogas is a clean and renewable energy, it is widely used, cheap and easy to obtain. It has replaced the use of natural gas.
沼氣進(jìn)行提純制取天然氣生產(chǎn)設(shè)備主要是依賴于大中型沼氣發(fā)酵系統(tǒng)工程或垃圾處理填埋場,可以通過對生活學(xué)習(xí)垃圾、餐廚垃圾、動物糞便、農(nóng)作物秸稈等生物質(zhì)厭氧發(fā)酵,獲得沼氣,然后我們通過膜分離法提純沼氣,使之達(dá)到提高天然氣的品質(zhì)。
The production equipment for purifying biogas to produce natural gas mainly depends on large and medium-sized biogas fermentation system engineering or waste treatment landfill. Biogas can be obtained by anaerobic fermentation of domestic and learning waste, kitchen waste, animal manure, crop straw and other biomass, and then we purify biogas by membrane separation method to improve the quality of natural gas.
