OSTI ID:6567077

Parametric analyses are described of an alcohol fuels plant producing 50 million gal/y of ethanol by the high temperature dilute acid hydrolysis of aspen wood or corn stover. Analyses were carried out using a computer simulation. The simulation performs material and energy balances, estimates capital and operating costs, and calculates the selling price of ethanol. Pretretments and delignification are shown to be justified only if the value of lignin is greater than $0.40/lb. Sensitivity analyses determine the effect of hydrolysis conditions on yield and selling price. Sugar concentration prior to fermentation is shown not to be justified.
