Using information published on the Purdue/Tsao Acid Solution Process for the Hydrolysis of Ligno-Cellulosic materials--specifically corn stovers--an engineering and cost analysis was performed for a battery limits facility to produce sufficient glucose syrup for 25 million gallons per year of ethanol. A capital investment estimate of 59 million dollars was derived. This estimate was based on vendor quoted equipment prices and a detailed consideration of all aspects of constructing the facility. The product transfer cost of the fermentable sugars--pentoses and hexoses--was estimated at 4.5 cents/pound. The major factor impacting the commercial feasibility of such a facility is the price assigned to the delivered corn stover. Although considerable development work on the process is required before it will be ready for commercialization, no technical problem was uncovered to preclude this commercialization.
