Exergy-Based Efficiency and Renewability Assessment of Biofuel Production
Environmental Science & Technology, 2005This study presents an efficiency and renewability analysis of the production of three biofuels: rapeseed methyl ester (RME), soybean methyl ester (SME) and corn-based ethanol (EtOH). The overall production chains have been taken into account: not only the agricultural crop production and the industrial conversion into biofuel, but also production of ...

A more general exergy function and its application to the definition of exergy efficiency
Energy, 2015Abstract An availability function which includes the usual functions exergy and flow exergy as special cases is defined and called exergy. The new definition of exergy is based on the concept of pressure energy, namely the work that must be done on a stationary external pressure field to build inside it the region of space occupied by the system ...

Through exergy approach to more efficient processes
2000This paper compares three different types of a turbine-converter-expander combination with respect to the exergetic efficiency. Converter stands for a combustion chamber, a Solid Oxide Fuel Cell and a reactor in which a chemical process is carried out. The exergy losses for the first examples are 22%. The exergy losses for the other two examples can be

Clarifying thermodynamic efficiencies and losses via exergy
Exergy, An International Journal, 2002Abstract The author explains his views that we need to clarify better what we mean by the terms efficiency and loss , and utilize exergy-based—rather than energy-based—measures of these quantities in order to ensure that the measures are meaningful and useful.

Calculation of exergy losses, exergy efficiency and cooling coefficient of refrigerant R22
International Journal of Science and Research ArchiveThis study presents a detailed analysis of the exergy losses, exergy efficiency, and cooling coefficient of performance (COP) for the refrigerant R22 in refrigeration systems. Exergy analysis, which considers both the quantity and quality of energy, is used to identify and quantify the irreversibilities within the system. The objective of this analysis
