摘要：
Exergy analysis is applied to a process for production of bio-ethanol from lignocellulosic. A tool based on Mathematica has been developed to calculate the exergy of compounds and streams of lignocellulosic ethanol production process. The whole process was simulated using the suitable chemical process simulation software (IPSEpro). Some different scenarios are analyzed for handling stillage waste from ethanol production. Parametric studies show the influence of the proper selection of scenario on exergy efficiency. It is shown that process integration reduces process irreversibilites. Internal use of waste streams for providing process heat and electricity as well as generation of some useful by-products such as animal feed and pellets using additional steps could increase exergy efficiency.
