Application of mathematical modelling in biorefinery processes design

A biorefinery is a facility that integrates biomass conversion processes and equipment to produce bio-products from biomass. Biorefineries will have to employ the best possible processes (for biomass cultivation, harvesting, storage and transport, pre-treatment, fermentation and bio-chemical conversion) to ensure efficient bio-based production. Nevertheless, numerous technical, strategic and commercial challenges have to be overcome to reinforce importance of bio-based production. Mathematical models can be used to simulate all aspects of bio-based production systems including the process design, production economics, supply logistics and environmental impacts. Those models can provide powerful tools to optimize biorefinery processes and evaluate its technical feasibility as well as economics and environmental impacts. In the presentation, examples of different mathematical models will be discussed, from the physical base model including kinetic, transport and diffusion equations to the statistical base model and data analyses. In the end, life cycle assessment analysis of the ethanol production from the corn stover will be provided as the example of modelling application in better understanding of the bio-based production environmental impact.
