Summary

Energy value based on lower heating value is calculated using a chemical equation that takes into account the chemical elements present in the raw material, using specific values ​​from the compressibility table to estimate its density. From the kinetic energy formula of the gas, the thermal energies for each component are obtained, which allows the specific density to be calculated in kilograms per cubic meter. This value is crucial to determine the energy efficiency of the process. The composition of natural gas and hydrogen are not identical for both phases, since natural gas varies depending on its composition and operating temperature, while hydrogen has a much lower density. For example, a liter of liquid H2 can offer a significantly higher energy value than a liter of gasoline due to its high density per volume and high calorific value. In the case of compounds, such as propane and butane, their density decreases as the temperature increases, which directly affects the final calculation of system performance. For applications requiring high precision, it is vital to employ the compressibility factor that relates pressure, temperature and density, ensuring that the calculated energy is real and consistent with the exact physical composition of the selected fluid.
