Ethane lower heating value

WebThe total amount of heat rejected during the process of combustion is called heating value of the fuel [16]. The heating value is usually measured in units of energy per unit mass of the substance, for example, kJ/kg, kcal/kg, or Btu/m 3. The three ways to express the heating values or calorific values of fuels are the lower heating value (LHV ... WebAll in all, the higher heating value of hydrogen is 18.2% above its lower heating value (142 MJ/kg vs. 120 MJ/kg). For hydrocarbons, the difference depends on the hydrogen content of the fuel. For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7%, respectively, and for natural gas about 11%.
