一、沼氣中含有硫化氫氣體,在燃燒使用前須要進行脫硫;
1、 Biogas contains hydrogen sulfide gas, which needs to be desulfurized before combustion;
二、沼氣中的甲烷成份含量為55—65%,而天然氣中的甲烷含量達90%以上,所以天然氣燃燒起來火力要強一些;
2、 The methane content in biogas is 55-65%, while the methane content in natural gas is more than 90%, so the fire power of natural gas is stronger;
三、天然氣的壓力大,沼氣的壓力小,由于壓力的關系,兩者之間灶具是不能通用的。
3、 The pressure of natural gas is high, but the pressure of biogas is low. Because of the pressure, the stoves between the two are not universal.
沼氣和天然氣在甲烷的含量的方面是有很大不同的。
Methane content of biogas and natural gas is very different.
一般沼氣中,甲烷占60%,二氧化碳約占40%。
In general, methane accounts for 60% and carbon dioxide accounts for about 40%.
天然氣無色、無味、無毒且無腐蝕性,主要成分為甲烷,也包括一定量的乙烷、丙烷和重質(zhì)碳氫化合物。還有少量的氮氣、氧氣、二氧化碳和硫化物。
Natural gas is colorless, tasteless, non-toxic and non corrosive. Its main component is methane, including a certain amount of ethane, propane and heavy hydrocarbons. There is also a small amount of nitrogen, oxygen, carbon dioxide and sulfide.
當然,燃燒性質(zhì)方面就會有所不同了;
Of course, the combustion properties will be different;
天然氣由于其熱值高,儲量大,適用范圍廣,一般采用液化天然氣運輸,或是天然氣管道運輸。而且遠距離運輸?shù)某杀疽蔡貏e高!
Because of its high calorific value, large reserves and wide application range, natural gas is generally transported by liquefied natural gas or natural gas pipeline. And the cost of long-distance transportation is particularly high!
而沼氣主要是用于農(nóng)村地區(qū),一般不需要遠距離運輸,而且沼氣不穩(wěn)定。如果非要運輸沼氣的話,估計也是可以的。但是可能產(chǎn)生的沼氣成分估計會有很大的變化,而且適用范圍不是很廣。
Biogas is mainly used in rural areas, generally does not need long-distance transportation, and biogas is unstable. If it is necessary to transport biogas, it is estimated that it is OK. However, it is estimated that the composition of biogas may vary greatly, and the scope of application is not very wide.
