沼气进行脱硫处理的必要性!

我们都知道,沼气是一种混合气体,它的主要成分是甲烷,其次有二氧化碳、硫化氢(H2S)、氮及其他一些成分。一般我们在使用沼气之前,都会进行脱硫处理,那么你知道这么做的原因吗?
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?
在沼气成分中甲烷含量为55%~70%、二氧化碳含量为28%~44%、硫化氢平均含量为0.034%。沼气的理化性质 沼气是一种无色、有味、有毒、有臭的气体,它的主要成分甲烷在常温下是一种无色、无味、无臭、无毒的气体。甲烷分子式是CH4,是一个碳原子与四个氢原子所结合的简单碳氢化合物。
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.
甲烷对空气的重量比是0.54,比空气约轻一半。甲烷溶解度很少,在20℃、0.1千帕时,100单位体积的水,只能溶解3个单位体积的甲烷。甲烷是简单的有机化合物,是的气体燃料。燃烧时呈蓝色火焰,zui高温度可达1?400?℃左右。纯甲烷每立方米发热量为36.8千焦。沼气每立方米的发热量约23.4千焦,相当于0.55千克柴油或0.8千克煤炭充分燃烧后放出的热量。从热效率分析,每立方米沼气所能利用的热量,相当于燃烧3.03千克煤所能利用的热量。
沼气脱硫
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.
对沼气进行脱硫处理,可以很大程度上提高沼气的使用率,提高利用率!此外,沼气中的硫化物如果不经过处理,还会对沼气燃烧设备造成腐蚀,加大危险事故的发生!
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.
