The quality term is referred to as “exergy”; however, equivalent names were found from our literature review, such as available energy, availability, work capability, etc. Exergy can be defined as the maximum available work that can be produced by the system as it comes into equilibrium with its surroundings. Exergy analysis was obtained as a function of the entropy relationships. Entropy is expressed in terms of system irreversibility.

Exergy analysis can be regarded as an advanced tool for analyzing energy conversion processes. The thermodynamic inefficiencies and irreversibility of the system design can be determined using the exergy tool. Moreover, the exergy concept was established to express the quality of energy utilized by the system. In addition, it demonstrates the disordered energy forms that are characterized by entropy. Conversely, the other ordered energy forms that are not involved in entropy are completely converted via work interactions and other energy forms. To determine the quality variable of various disordered energies in thermal and chemical plants, the universal quality standard, exergy, is used. Exergy can be defined as the maximum work that can be obtained from the available input energy using the environmental state conditions as the reference parameters.

The exergy of fuels can be evaluated by multiplying the Beta factor by the LHV.

The Beta can be calculated using different correlations as mentioned above.

Chemical exergy fraction = 1.0401 + 0.1728 H/C + 0.0432 O/C + 0.2169 (S/C) (1 − 2.0628 H/C )
