Higher heating value methane

WebIf the water vapor produced is not condensed, then the heat of combustion of methane is 802.3 kJ/mole, with the difference being the latent heat of condensation of the water vapor. The greater value—based on forming liquid water—is known in the industry as the higher heating value (HHV) of methane. Web3 de jul. de 2024 · Methane: 890 k J / m o l 16 g / m o l = 55.6 k J / g Propane: 2200 k J / m o l 44 g / m o l = 50 k J / g For the enviromental aspect of C O X 2 emissions, the relevant value is the heat of combustion per mole of carbon atoms. It is 890 k J / m o l for methane, but 2200 k J / m o l for propane, which is roughly 730 k J / m o l for carbon.
