We present an optimization based framework to perform a comprehensive technoeconomic, environmental, and societal assessment of an alternative energy refinery that will convert biomass to the liquid transportation fuels (BTL) gasoline, diesel, and kerosene. Rigorous process design, global optimization, and process synthesis strategies will be utilized [4-11] to determine the optimal plant topology of a BTL refinery that minimizes the overall cost of liquid fuels production. The cost of utility generation and wastewater treatment is treated using a simultaneous heat, power, and water integration within the process synthesis model. Multiple case studies are presented to investigate the effect of biomass type, biomass moisture content, plant capacity, and product distribution on the optimal process topology, total plant cost, and break-even oil price. Major topological decisions from the optimization model and the result on plant capital cost, total operational cost, and the process utility network will be discussed.
