Abstract
The present paper proposes a flexible modular linear model of decision-making for the
selection of processes and unit operations for lignocellulosic bioethanol production. The
methodology begins by suppressing the commonly accepted bilinear restrictions for
flows and compositions, and there after allows building the identity of the synthesis
problem by easing the introduction of components, interconnection specifications or
block characteristics and performance. A case study in second generation ethanol
production using biomass from sugarcane bagasse as raw material is presented to test
the developed process synthesis tool, using GAMS. Results show that the diluted acid
pretreatment, the SSCF configuration for hydrolysis and fermentation, and the
extractive distillation as the selected blocks. The methodology demonstrated a low
computational cost and a simplified management of the problem complexity. These
approach is suitable for process screening when missing or restricted data from the
process alternatives is available.
