Supercritical biodiesel production: Feasibility of energy integration with a bioethanol production process

Biodiesel can be obtained from raw materials with high content of free fatty acids through supercritical processes, which allows obtaining high-quality fuel; nevertheless, such processes imply operating under pressure and temperature. On the other hand, low-cost lignocellulosic biomass converted to bioethanol. Both integrated energy flows, expecting reductions on total requirements environmental impact. Therefore, in this work integration flows between biodiesel bioethanol is performed, along its impact terms annual cost The are first as separated entities, then effect integrating both a biorefinery scheme analyzed. According results, heat reducing around 15% associated exchangers. Moreover, even capital costs for process.
