Web1 de mar. de 2024 · The higher heating values (HHVs) of the hydrocarbon compounds can be calculated based on the carbon (C) and hydrogen (H) contents of the chemical structures. HHVs (MJ / kg) as a function of the carbon (C) and hydrogen (H) fractions of N-saturated hydrocarbons can be calculated by the following equation: Web29 de mar. de 2024 · hfg = Heat of vaporization of water per unit mass mH20 = Mass of water The relationship between HHV and LHV can be derived from the basic combustion equation. The combustion equation for pure methane (CH4), which is the primary constituent of natural gas, is: CH4 + 2O2 ^ CO2 + 2H20 WebLHV = 50.025 MJ/kg The LHV is calculated assuming that water remains in the gas phase. However, more energy can be extracted from the mixture if this water is condensed. This value is the higher heating value (HHV). The ideal gas mixture model used here cannot calculate this contribution directly. high valine blood levels
