Integration of bioethanol as an in-process material in biorefineries using mass pinch analysis

► Bioethanol integration approach based on mass pinch analysis. ► Bioethanol exchange network design to maximise recovery between sources and demands. ► Graphical targeting approach allows minimum fresh bioethanol consumption. ► Biorefinery debottlenecking by bioethanol integration and added value co-production. ► Graphical targeting and cost-benefit analyses for synthesis and retrofit design.
