Heating Values of Natural Gas - EnggCyclopedia

Heating value of a natural gas is an important indicator of its overall value as a fuel. The heating value of a substance is the energy released upon combustion of a substance at standard conditions. The heating value can be measured as energy released per unit mass, unit volume or unit mole of a substance. For mixtures, the heating value can
