For these reasons, the modern approach to process analysis uses
the exergy analysis, which provides a more realistic view of the
process and a useful tool for engineering evaluation [4]. As a matter
of fact, many researchers [5–8] have recommended that exergy
analysis be used to aid decision making regarding the allocation of
resources (capital, research and development effort, optimization,
life cycle analysis, materials, etc.) in place of or in addition to energy
analysis [3]. Exergy analysis has become a key aspect in providing
a better understanding of the process, to quantify sources of
inefficiency, and to distinguish quality of energy used [9]. Some
researchers dedicated their studies to component exergy analysis
and efficiency improvement [10,11]; others focused on systems design
and analysis [12–16].
