文摘

A techno-economic analysis (TEA) compared two biorefinery processing scenarios. Decentralized biorefineries employing AFEX require the highest capital cost. A centralized biorefinery using AHP has lower capital cost but higher water use. The best-case AFEX scenario yields the lowest minimum ethanol selling price (MESP). Biomass cost and alkali recovery exert a significant impact on MESPs.
