Bioethanol National Renewable Energy

For the purpose of conceptual design of the bioethanol plant, Aspen Plus will be used as the flowsheet simulator. However, most of the key components involved in the process are not defined in the standard Aspen Plus property databases, and therefore their physical property data are not available. The National Renewable Energy Laboratory (NREL) has developed a database that includes a complete set of properties for the currently identifiable compounds in the ethanol process [28].

Data included shows the process parameters used for process simulation (Stenberg et af, 1998 Wooley et ah, 7 999 Aden et ai, 2002 Cal be Zacchi, 2002 Soderstrom et ak, 2003 National Renewable Energy Laboratory, 2004 Soderstrom et ai, 2004 Sassner et ai, 2008 Fornell Berntsson, 2009)...
