Abstract:
This work presents a robust optimization approach for the synthesis of integrated biorefineries that able to handle uncertainties of product demands. To convert biomass into value-added products, ranging from biofuels to specialty chemicals, an integrated processing facility known as integrated biorefineries is needed. Due to the high degree of integration with various biomass conversion and synthesis technologies, integrated biorefineries are able to produce multiple products efficiently. Uncertainties in final product demands and its association with biomass availability are the important parameters for synthesis of integrated biorefinery. Therefore, such parameters should be taken into consideration. The proposed problem is formulated as a mixed integer non-linear programming (MINLP) and it is solved with given data on projection of multiple product demands scenarios. Each scenario is assumed to have an expected probability of occurrence. The optimization problem is a single step robust optimization program with the objective function to maximize the average net present value (NPV) of revenue for all scenarios. The penalty cost of nonconformity to the product demand of any scenario is also taken into consideration in the objective function. A black liquor biorefinery case study is solved where two scenarios with a product portfolio comprised of dimethyl ether (DME) and Fischer-Tropsch crude (FT) are considered.
