沼氣提純后能用到哪？這五大應(yīng)用場景超實(shí)用

　　Where can biogas be used after purification? These five application scenarios are super practical

　　原本被當(dāng)作廢棄物處理的沼氣，經(jīng)過專業(yè)提純后，搖身一變就能成為高價(jià)值的清潔能源，應(yīng)用場景遍布交通、工業(yè)、民生等多個(gè)領(lǐng)域。很多人只知道沼氣能發(fā)電，卻不清楚提純后的生物天然氣有這么多實(shí)用用途。今天就給大家詳細(xì)科普，沼氣提純后到底能用到哪些地方，看看它如何從“農(nóng)場廢棄物”升級為貫穿生產(chǎn)生活的優(yōu)質(zhì)能源。

　　Biogas, which was originally treated as waste, can be transformed into high-value clean energy after professional purification, with applications in various fields such as transportation, industry, and people's livelihoods. Many people only know that biogas can generate electricity, but they are not aware of the many practical uses of purified biogas. Today, we will give you a detailed explanation of where biogas can be used after purification, and see how it can be upgraded from "farm waste" to high-quality energy that runs through production and life.

　　第一個(gè)常見場景是車用燃?xì)狻＝?jīng)提純后的高純度甲烷，能直接作為車用天然氣，適配汽車、船舶等各類交通工具?，F(xiàn)在不少城市的出租車、公交車都已經(jīng)改用天然氣，而提純后的沼氣完全能達(dá)到車用標(biāo)準(zhǔn)。對比傳統(tǒng)燃油，它不僅清潔環(huán)保，燃燒后幾乎不產(chǎn)生顆粒物和有害氣體，還能降低出行成本——天然氣的價(jià)格通常比汽油、柴油低不少，對運(yùn)營車輛來說，長期使用能節(jié)省一大筆開支。像一些大型物流公司、港口碼頭，已經(jīng)開始嘗試用提純后的沼氣作為運(yùn)輸車輛和船舶的燃料，既響應(yīng)了環(huán)保政策，又降低了運(yùn)營成本。

　　The first common scenario is car gas. Purified high-purity methane can be directly used as natural gas for vehicles, suitable for various types of transportation such as cars and ships. Nowadays, many taxis and buses in cities have switched to natural gas, and the purified biogas can fully meet the standards for vehicles. Compared to traditional fuels, it is not only clean and environmentally friendly, but also produces almost no particulate matter and harmful gases after combustion. It can also reduce travel costs - the price of natural gas is usually much lower than gasoline and diesel, and for operating vehicles, long-term use can save a lot of expenses. Some large logistics companies and port terminals have begun to try using purified biogas as fuel for transportation vehicles and ships, which not only responds to environmental policies but also reduces operating costs.

　　第二個(gè)重要場景是工業(yè)用氣。在工業(yè)生產(chǎn)中，提純后的沼氣可以作為燃料，用于鍋爐燃燒、工業(yè)加熱等多個(gè)環(huán)節(jié)，完美替代煤炭、重油等傳統(tǒng)能源。工業(yè)領(lǐng)域是能源消耗大戶，也是污染物排放的主要來源之一，用清潔的沼氣替代傳統(tǒng)能源，能大幅減少二氧化硫、氮氧化物等污染物的排放，幫助企業(yè)達(dá)到環(huán)保要求。比如食品加工廠的蒸汽鍋爐、建材廠的加熱工序，都能改用提純后的沼氣，不僅環(huán)保達(dá)標(biāo)，能源成本也更可控，尤其適合周邊有大型養(yǎng)殖場、污水處理廠的工業(yè)企業(yè)，能實(shí)現(xiàn)能源就近供應(yīng)。

　　The second important scenario is industrial gas. In industrial production, purified biogas can be used as fuel for various processes such as boiler combustion and industrial heating, perfectly replacing traditional energy sources such as coal and heavy oil. The industrial sector is a major energy consumer and one of the main sources of pollutant emissions. Replacing traditional energy with clean biogas can significantly reduce emissions of pollutants such as sulfur dioxide and nitrogen oxides, helping companies meet environmental protection requirements. For example, steam boilers in food processing plants and heating processes in building materials factories can be converted to purified biogas, which not only meets environmental standards but also has more controllable energy costs. It is particularly suitable for industrial enterprises with large livestock farms and sewage treatment plants in the surrounding area, and can achieve energy supply nearby.

　　第三個(gè)場景是民用燃?xì)?，這也是和我們?nèi)粘Ｉ钭钯N近的用途。提純后的沼氣經(jīng)過檢測達(dá)標(biāo)后，能通過城市燃?xì)夤芫W(wǎng)輸送到居民家中，作為做飯、取暖的生活用氣，和我們現(xiàn)在使用的天然氣沒有區(qū)別。隨著清潔能源推廣政策的推進(jìn)，越來越多的地區(qū)開始完善燃?xì)夤芫W(wǎng)，而沼氣提純后作為民用燃?xì)?，既能豐富清潔能源供應(yīng)渠道，又能讓居民用上更經(jīng)濟(jì)的燃?xì)?。對農(nóng)村地區(qū)來說，周邊養(yǎng)殖場的沼氣提純后還能實(shí)現(xiàn)“村域供氣”，解決農(nóng)村居民的清潔能源使用問題。

　　The third scenario is civilian gas, which is also the most closely related use to our daily life. After being purified and tested to meet the standards, the biogas can be transported to residents' homes through urban gas pipelines as cooking and heating gas, which is no different from the natural gas we currently use. With the promotion of clean energy policies, more and more regions are improving their gas pipelines. Purified biogas, as a civilian gas, can not only enrich the supply channels of clean energy, but also enable residents to use more economical gas. For rural areas, the purification of biogas from surrounding farms can also achieve "village gas supply", solving the problem of clean energy use for rural residents.

　　除了作為燃料，提純后的沼氣還能作為化工原料，這是延伸產(chǎn)業(yè)鏈價(jià)值的重要方向。高純度的甲烷是化工生產(chǎn)的基礎(chǔ)原料，能用于合成甲醇、乙烯、丙烯等多種化工產(chǎn)品。這些化工產(chǎn)品又能進(jìn)一步加工成塑料、橡膠、涂料等生活用品和工業(yè)材料，讓沼氣從“能源”升級為“工業(yè)原料”，大幅提升其經(jīng)濟(jì)價(jià)值?，F(xiàn)在已有部分化工企業(yè)嘗試用提純后的沼氣作為原料，既降低了對化石原料的依賴，又實(shí)現(xiàn)了廢棄物的資源化利用，形成了“環(huán)保+產(chǎn)業(yè)”的雙贏模式。

　　In addition to being used as fuel, purified biogas can also be used as a chemical raw material, which is an important direction for extending the value of the industrial chain. High purity methane is the basic raw material for chemical production and can be used to synthesize various chemical products such as methanol, ethylene, and propylene. These chemical products can be further processed into daily necessities and industrial materials such as plastics, rubber, coatings, etc., upgrading biogas from an "energy" to an "industrial raw material" and greatly enhancing its economic value. Some chemical companies have now attempted to use purified biogas as raw material, which not only reduces their dependence on fossil fuels, but also realizes the resource utilization of waste, forming a win-win model of "environmental protection+industry".

　　第五個(gè)場景是發(fā)電儲能。這也是大家相對熟悉的用途，提純后的沼氣可以通入燃?xì)獍l(fā)電機(jī)組發(fā)電，產(chǎn)生的電力既能滿足企業(yè)自身使用，多余的電力還能并入電網(wǎng)，獲得電費(fèi)收益。更重要的是，它還能配合儲能系統(tǒng)調(diào)節(jié)能源供應(yīng)——比如風(fēng)能、太陽能受天氣影響大，發(fā)電不穩(wěn)定，而沼氣發(fā)電能穩(wěn)定產(chǎn)出，在風(fēng)光發(fā)電不足時(shí)補(bǔ)充供電，保障能源系統(tǒng)的穩(wěn)定運(yùn)行。像大型養(yǎng)殖場、污水處理廠，本身產(chǎn)氣穩(wěn)定，用提純后的沼氣發(fā)電儲能，能實(shí)現(xiàn)能源自給自足，甚至對外供電盈利。

　　The fifth scenario is power generation and energy storage. This is also a relatively familiar use for purified biogas, which can be fed into gas generators to generate electricity. The generated electricity can meet the needs of the enterprise itself, and the excess electricity can also be integrated into the power grid to generate electricity revenue. More importantly, it can also cooperate with energy storage systems to regulate energy supply - for example, wind and solar energy are greatly affected by weather and have unstable power generation, while biogas power generation can produce stable output and supplement power supply when wind and solar power generation is insufficient, ensuring the stable operation of the energy system. Large scale breeding farms and sewage treatment plants, with stable gas production and the use of purified biogas for power generation and energy storage, can achieve energy self-sufficiency and even generate profits from external power supply.

　　總結(jié)下來，沼氣提純后的應(yīng)用場景覆蓋車用、工業(yè)、民用、化工、發(fā)電儲能五大領(lǐng)域，從交通出行到工業(yè)生產(chǎn)，再到日常生活，都能看到它的身影。這也充分說明，沼氣不是“沒用的廢棄物”，而是極具價(jià)值的“綠色寶藏”，經(jīng)過提純處理后，能真正融入能源體系，為綠色能源轉(zhuǎn)型貢獻(xiàn)力量。對企業(yè)來說，了解這些應(yīng)用場景，能更好地規(guī)劃沼氣資源化利用方案；對我們普通人來說，認(rèn)識沼氣提純后的價(jià)值，也能更清晰地理解清潔能源推廣的重要意義。如果大家身邊有沼氣相關(guān)的項(xiàng)目，不妨多關(guān)注一下它的應(yīng)用方向，說不定未來我們的出行、生活都能更頻繁地用到這份“循環(huán)能源”。

　　In summary, the application scenarios of purified biogas cover five major fields: automotive, industrial, civilian, chemical, and power generation and energy storage. Its presence can be seen in transportation, industrial production, and daily life. This also fully demonstrates that biogas is not a "useless waste", but a highly valuable "green treasure". After purification and treatment, it can truly integrate into the energy system and contribute to the transformation of green energy. For enterprises, understanding these application scenarios can better plan the utilization of biogas resources; For us ordinary people, understanding the value of purified biogas can also provide a clearer understanding of the importance of promoting clean energy. If you have projects related to biogas around you, you may want to pay more attention to its application direction. Maybe in the future, we can use this "circular energy" more frequently in our travel and daily life.
