The background of bioethanol as an alternative to conventional fuels is analyzed with the aim of examining the efficiency of bioethanol production by first (sugar-based) and second (cellulose-based) generation processes. Energy integration is of paramount importance for a complete recovery of the processes’ exergy potential. Based upon literature data and our own findings, exergy analysis is shown to be an important tool in analyzing integrated ethanol production from an efficiency and cost perspective. View Full-Text
