N2 - Biofuels have been promoted as a possible solution to provide renewable fuels and diminish society's dependence on non-renewable energy sources. However, there are a plethora of possible biofuel product and processes, and an ideal choice is unclear. Furthermore, economic and environmental metrics must be chosen that best analyze the performance of the selected pathway. This work presents a functional unit based approach towards optimization of product and process networks. The mass of ethanol produced in a biofuels network is chosen as the functional unit (FU), and the production cost and global warming potential per FU are computed. Solving the resulting NLFP (nonlinear, fractional program) is reduced to iteratively solving a sequence of MILP by integrating a piecewise linear approximation algorithm using branch and refine methods with the parametric algorithm. A case study processing up to 100,000. tons/hr of a variety of biomass to meet an ethanol demand of 2.88. Mgal/yr is presented.
