Abstract

Several alternative process pathways including biochemical and thermochemical conversions are available for the second generation biorefineries. In this view conceptual design of a superstructure and optimization methods for process synthesis are widely used in order to find the optimal process flowsheet (Stefanakis et al., 2014). In the present work the flowsheet resulting from the economic optimization of a multiproduct lignocellulosic biorefinery superstructure was simulated by a process simulator (Aspen Plus). As a result, rigorous methods were used to calculate the stream thermodynamic properties and to model the process units. Economic analysis was applied to assess the economic feasibility of the process. Sensitivity analysis on the size of the plant, the product prices and the biomass price was carried out as well.
