沼气提纯净化有着良好的前景,其对沼气的应用也起着重要的作用!今天,沼气提纯的小编就给大家介绍一下沼气提纯净化技术的利用现状!
Biogas purification and purification has a good prospect, and it also plays an important role in the application of biogas. Today, the small edition of biogas purification will introduce to you the current situation of the utilization of biogas purification and purification technology!
沼气中含有硫化氢,分子式为H2S,硫化氢为易燃危化品,与空气混合能形成爆炸性混合物,遇明火、高热能引起燃烧爆炸,加上硫化氢遇水后会对钢材产生较强的腐蚀特性,因此沼气提纯精制生物天然气的预处理工序的核心即是脱除硫化氢。
Biogas contains hydrogen sulfide, the molecular formula is H2S, hydrogen sulfide is flammable and dangerous chemicals, which can form explosive mixture when mixed with air. When exposed to open fire and high heat, it can cause combustion and explosion, and when hydrogen sulfide is exposed to water, it will produce strong corrosion characteristics on steel. Therefore, the core of the pretreatment process for biogas purification and refining is that It is the removal of hydrogen sulfide.
不同的有机废弃物在厌氧状态下产生的沼气中的硫化氢浓度有高有低,差异比较大。造纸工业、发酵工业等由于在生产过程中有含硫的介质加入,生产废水产生的沼气含硫化氢的浓度便比较高。如造纸行业的沼气可高达10000-35000ppm,淀粉工业沼气一般在10000ppm左右,生活垃圾填埋沼气则由于产生过程中相对较少有硫介质参与,因此硫化氢含量较低,一般在1000ppm以内。
沼气提纯
The concentration of hydrogen sulfide in biogas produced by different organic wastes under anaerobic condition is high or low, and the difference is large. The concentration of hydrogen sulfide in biogas produced from wastewater is relatively high in papermaking industry and fermentation industry due to the addition of sulfur-containing medium in the production process. For example, biogas in paper industry can reach as high as 10 000-35 000 ppm, starch industry biogas is generally about 10 000 ppm, and domestic waste landfill biogas is relatively low in hydrogen sulfide content, generally less than 1 000 ppm due to the relatively little sulfur medium involved in the production process.
在我国,目前沼气的生产加工技术和商业化运行系统也已经逐渐成熟,通过自主创新、引进并消化吸收了国外成熟先进的高含固量的有机废弃物厌氧消化技术,其中以谷物秸秆、畜禽粪便、城市有机垃圾为处理对象的大型沼气工程也取得了突破性进展,因此,相应的沼气净化提纯工艺技术也得到发展,形成了一系列相对比较成熟的技术。
In China, the production and processing technology of biogas and commercial operation system have gradually matured. Through independent innovation, introduction and digestion, advanced anaerobic digestion technology of high solid content organic wastes abroad has been absorbed. Among them, large-scale biogas with grain straw, livestock and poultry manure, and municipal organic waste as its treatment objects has been introduced. The project has also made breakthrough progress, so the corresponding biogas purification and purification technology has also been developed, forming a series of relatively mature technologies.
