Combustion value of refinery gas
Thread Content
Please help to find out the combustion value of gas
The calorific value of gas must be calculated based on its composition
It seems like everyone is calculating based on 7600:lol
Friends upstairs, please provide the definition and unit of 7600, as well as the calculation formula for determining it based on its components
There are uniform regulations for this: the calorific value of fuel gas is equivalent to 950 kg of standard oil per ton.
The main components of refinery gas are C1 and C2; when calculating energy consumption, we consider both the gas and vacuum residue to have a combustion value of 10,000 Kcal per kilogram, which is equivalent to the combustion value of 1 kilogram of standard oil.
The combustion values of gas in different devices vary greatly, with the difference potentially reaching up to 50%!
Due to different compositions, the calorific values vary significantly； If conducting energy consumption analysis, it is best to carry out a composition analysis once a week and calculate it manually; (by using the composition details, along with the heat value of CH4 and other components as well as the proportion of each component, it is possible to make such calculations)
It’s hard to answer your question, OP! ! Since the composition varies, the low calorific value also changes; I once calculated that it’s around 32 Mj/Nm3 for our company! ! !
