I want to say is methane, natural gas, liquefied petroleum gas to methane content to distinguish, what are the basis and norms or standards to illustrate the percentage, they contain methane gas, biogas, what are the content of methane in the liquefied petroleum gas, what basis and norms or standards.
Liquefied petroleum gas is mainly composed of propane, butane, propylene and butylene, but also contains a small amount of ethane and pentane, does not contain methane; so the same volume of liquefied petroleum gas calorific value is much higher than natural gas
Natural gas and liquefied petroleum gas to conventional fossil energy, gas and town gas design handbook design rules for what is natural gas and liquefied petroleum gas has a clear definition, conventional gas component content can refer to your regular teacher for the "gas". The main components of natural gas is methane, methane the content above 90%
So the same volume of liquefied petroleum gas calorific value is much higher than natural gasAlthough methane is also a major component of methane content, but much smaller than natural gas, methane content is 50% ~ 80%, with a small amount of hydrogen and hydrogen sulfide, besides non combustible gases (carbon dioxide and nitrogen) content is generally 20%~45%. specific understanding of biogas, biogas can find some aspects of the textbook look.In the three kind of gas, the calorific value from high to low is liquefied petroleum gas, natural gas and biogasThere is no clear place to exchange
