沼氣進(jìn)行脫硫處理的必要性!

我們都知道,沼氣是一種混合氣體,它的主要成分是甲烷,其次有二氧化碳、硫化氫(H2S)、氮及其他一些成分。一般我們?cè)谑褂谜託庵埃紩?huì)進(jìn)行脫硫處理,那么你知道這么做的原因嗎?

As we all know, biogas is a mixed gas, its main component is methane, followed by carbon dioxide, hydrogen sulfide (H2S), nitrogen and other components. Usually, before we use biogas, we will do desulfurization treatment. Do you know why we do this?
在沼氣成分中甲烷含量為55%~70%、二氧化碳含量為28%~44%、硫化氫平均含量為0.034%。沼氣的理化性質(zhì) 沼氣是一種無(wú)色、有味、有毒、有臭的氣體,它的主要成分甲烷在常溫下是一種無(wú)色、無(wú)味、無(wú)臭、無(wú)毒的氣體。甲烷分子式是CH4,是一個(gè)碳原子與四個(gè)氫原子所結(jié)合的簡(jiǎn)單碳?xì)浠衔铩?/div>
The methane content is 55%-70%, the carbon dioxide content is 28%-44%, and the average content of hydrogen sulfide is 0.034%. Biogas is a colorless, odorous, toxic and odorous gas. Its main component, methane, is a colorless, odorless, odorless and non-toxic gas at room temperature. The formula for methane is CH4, a simple hydrocarbon that combines carbon atoms with four hydrogen atoms.
甲烷對(duì)空氣的重量比是0.54,比空氣約輕一半。甲烷溶解度很少,在20℃、0.1千帕?xí)r,100單位體積的水,只能溶解3個(gè)單位體積的甲烷。甲烷是簡(jiǎn)單的有機(jī)化合物,是的氣體燃料。燃燒時(shí)呈藍(lán)色火焰,zui高溫度可達(dá)1?400?℃左右。純甲烷每立方米發(fā)熱量為36.8千焦。沼氣每立方米的發(fā)熱量約23.4千焦,相當(dāng)于0.55千克柴油或0.8千克煤炭充分燃燒后放出的熱量。從熱效率分析,每立方米沼氣所能利用的熱量,相當(dāng)于燃燒3.03千克煤所能利用的熱量。
沼氣脫硫
The weight ratio of methane to air is 0.54, which is about half as light as air. The solubility of methane is very low. At 20 C and 0.1 kPa, 100 units of water can only dissolve 3 units of methane. Methane is a simple organic compound, a gas fuel. When burning, the flame is blue, and the high temperature of Zui can reach 1? 400??? Pure methane has a calorific value of 36.8 kilojoules per cubic meter. The calorific value of biogas is about 23.4 kJ per cubic meter, which is equivalent to the calorific value of 0.55 kg diesel oil or 0.8 kg coal when fully burned. From the analysis of thermal efficiency, the amount of heat that biogas can utilize per cubic meter is equivalent to the amount of heat that can be utilized by burning 3.03 kg of coal.
對(duì)沼氣進(jìn)行脫硫處理,可以很大程度上提高沼氣的使用率,提高利用率!此外,沼氣中的硫化物如果不經(jīng)過(guò)處理,還會(huì)對(duì)沼氣燃燒設(shè)備造成腐蝕,加大危險(xiǎn)事故的發(fā)生!
Desulfurization of biogas can greatly improve the utilization rate and utilization rate of biogas. In addition, if the sulfide in biogas is not treated, it will cause corrosion to the biogas combustion equipment and increase the occurrence of dangerous accidents.
