其实沼气和天然气的成分差不多，但是应用普及程度却差了很多，那你知道为什么沼气不能像天然气一样大量普及吗？下面我们就一起看一下沼气提纯设备厂家的解释吧！

In fact, the composition of biogas and natural gas is similar, but the popularization of biogas is much worse. Do you know why biogas can not be popularized as much as natural gas? Now let's take a look at the explanation of the manufacturer of biogas purification equipment.

一、沼气中含有硫化氢气体，在燃烧使用前必须要进行脱硫；

1. Biogas contains hydrogen sulfide gas, which must be desulfurized before combustion.

二、沼气中的甲烷成份含量为55—65%，而天然气中的甲烷含量达90%以上，所以天然气燃烧起来火力要强一些；

2. The methane content in biogas is 55-65%, while the methane content in natural gas is more than 90%, so the firepower of natural gas is stronger.

三、天然气的压力大，沼气的压力小，由于压力的关系，两者之间灶具是不能通用的。

3. The pressure of natural gas is high and the pressure of biogas is low. Because of the pressure relationship, the cooker between the two can not be used.

沼气和天然气在甲烷的含量的方面是有很大不同的。

Biogas and natural gas differ greatly in the content of methane.

一般沼气中，甲烷占60％，二氧化碳约占40％。

In general, methane accounts for 60% and carbon dioxide accounts for 40%.

天然气无色、无味、无毒且无腐蚀性，主要成分为甲烷，也包括一定量的乙烷、丙烷和重质碳氢化合物。还有少量的氮气、氧气、二氧化碳和硫化物。

Natural gas is colorless, odorless, non-toxic and non-corrosive. Its main component is methane, which also includes a certain amount of ethane, propane and heavy hydrocarbons. There are also small amounts of nitrogen, oxygen, carbon dioxide and sulfides.

当然，燃烧性质方面就会有所不同了;

Of course, the combustion properties will be different.

天然气由于其热值高，储量大，适用范围广，一般采用液化天然气运输，或是天然气管道运输。而且远距离运输的成本也特别高！

Because of its high calorific value, large reserves and wide application range, natural gas is usually transported by liquefied natural gas or by natural gas pipeline. And the cost of long-distance transportation is particularly high!

而沼气主要是用于农村地区，一般不需要远距离运输，而且沼气不稳定。如果非要运输沼气的话，估计也是可以的。但是可能产生的沼气成分估计会有很大的变化，而且适用范围不是很广

The biogas is mainly used in rural areas, generally does not need long-distance transportation, and the biogas is unstable. It is also possible to transport biogas if necessary. However, the estimation of biogas composition may vary greatly, and the scope of application is not very wide.
