Abstract:

This paper presents an analysis of the production of lignocellulosic bio-ethanol using wheat straw as feedstock for the Mexican economic and agriculture context. The analysis has three points of view: technical, economic and energetic. Two biorefinery conceptual designs were proposed: a single product plant (SPP) (ethanol) and a co-production biorefinery (CPB) (ethanol and hydrogen). Both designs are equipped with an electricity co­generation stage. An economic sensitivity analysis was performed to obtain the ethanol total production cost (TPC), with plant capacity and raw material polysaccharides content (%pc) (i.e. feedstock cost) as parameters. The best results were 0.92 and 1.28 USD/L, for a 2,100 ton DB/day plant capacity and 80 %pc for SPP and CPB, respectively. An interval of plant capacities and %pc was identified with variations of no more than 20% of the minimum TPC in order to explore smaller capacity facilities that can fit the agriculture the Mexican agriculture. The end/use energy ratio was employed to study the biorefineries energy efficiency. Values over 100% were found. Finally a study for the end use of coproducts in biorefinery was carried out. Burning the biogas and selling the hydrogen can improve, at least, the economy of the plant increasing 5% the IRR.
