近些年,因為環(huán)境的問題與能源污染問題越來越嚴重,生物質(zhì)能已經(jīng)逐漸成為新能源的研究途徑之一,這也衍生出了關(guān)于沼氣能源提純制取的相關(guān)研究。目前,大力發(fā)展天然氣產(chǎn)業(yè),已經(jīng)成為我們國家能源結(jié)構(gòu)優(yōu)化和實現(xiàn)低碳發(fā)展的重要戰(zhàn)略途徑,是一項非常重要的舉措。因為我國的天然氣目前正處于一個快速發(fā)展的階段,供應和消耗量都在快速提升,所以時常會出現(xiàn)天然氣短缺的局面。為了應對這一局面,并從理論上的角度來看,出于對能源問題和環(huán)境問題的雙重思考,沼氣提純制取生物天然氣的研發(fā),不僅可以實現(xiàn)高產(chǎn)量天然氣資源,同時還能夠?qū)崿F(xiàn)較為突出的環(huán)境保護作用,經(jīng)濟價值與社會價值均較為突出,生物質(zhì)能等可再生能源的發(fā)展可引起極大的關(guān)注。沼氣提純制取生物天然氣作為一種新型可再生能源,開發(fā)利用符合國家產(chǎn)業(yè)政策,商業(yè)價值巨大,開發(fā)利用前景非常廣闊。
In recent years, due to the increasingly serious environmental problems and energy pollution problems, biomass energy has gradually become one of the research ways of new energy, which also derived the relevant research on biogas energy purification. At present, vigorously developing the natural gas industry has become an important strategic way to optimize the energy structure and realize low-carbon development in our country, and it is a very important measure. Because China's natural gas is in a stage of rapid development, supply and consumption are rising rapidly, so there is often a shortage of natural gas. In order to deal with this situation, and from a theoretical point of view, out of the dual consideration of energy and environmental problems, the research and development of biogas purification to produce biological natural gas can not only achieve high-yield natural gas resources, but also achieve a more prominent role in environmental protection. The economic value and social value are more prominent, and the development of renewable energy such as biomass energy can be improved It has aroused great concern. As a new type of renewable energy, the development and utilization of biogas is in line with the national industrial policy, with huge commercial value and broad development and utilization prospects.
沼氣是由多種氣體的混合物,主要含有甲烷和二氧化碳,甲烷占55%~70%,二氧化碳占30%~45%。沼氣提純制取生物天然氣(以下簡稱沼氣提純)是指利用厭氧發(fā)酵處理產(chǎn)生沼氣,經(jīng)脫硫、脫碳、脫水、加壓等工藝后成為生物天然氣(bio-natural gas,簡稱BNG)進行利用,不僅能夠充分的進行廢物利用,還節(jié)能環(huán)保,是一種綠色能源,非常有發(fā)展前景。
Biogas is a mixture of many gases, mainly containing methane and carbon dioxide. Methane accounts for 55% ~ 70% and carbon dioxide accounts for 30% ~ 45%. Biogas purification to produce biogas (hereinafter referred to as biogas purification) refers to the biogas produced by anaerobic fermentation. After desulfurization, decarbonization, dehydration, pressurization and other processes, biogas becomes biological natural gas (bng) for efficient utilization. It can not only fully utilize waste, but also save energy and environmental protection. It is a kind of green energy and has great development prospects.
