A stover-to-ethanol plant produces 40,000 tonne/ year of ethanol and contains 8 functional units: feedstock handling, pretreatment, simultaneous saccharification/fermentation distillation, solid/ sirup separation, wastewater treatment, boilers, and turbogeneration/utilities (McAloon et al., 2000). Estimate the FCI of the plant using the empirical correlation based on the work of Bridgwater and Mumford (1979).
