Summary

This study concerns the preliminary economic feasibility of a process for converting agricultural waste (wheat straw) to fuel grade ethanol through enzymatic hydrolysis. A preliminary design for the process was developed on the basis of research concepts described in the literature. The base case design is for a 25 million gal/yr plant for 95 vol % ethanol from wheat straw. The preliminary design included material and energy balances and major equipment specifications and sizing, which in turn were used for estimating the required capital investment. Estimates of process operating costs and required selling prices were based on typical industrial conditions. The sensitivity of product ethanol cost to changes in key operating variables was determined in order to indicate where future process improvements are needed and more R and D effort is warranted.
