Thermal Process Engineering Project Green Biorefinery Realisation of a novel process § Licence based on Austrian Patent AT 000000504206 (2008) § General definition Biorefinery: „A biorefinery is a facility that integrates biomass conversion processes and equipment to produce fuels, power and chemicals from biomass. The biorefinery concept is analogous to today‘s petroleum refineries, which produce multiple fuels and products from petroleum“ (http: //www. nrel. gov/biomass/biorefinery. html) Fig: Map of Austria Achema 2012 Fig: Ultrafiltration: housing for ceramic module Institute of Chemical Engineering page 2
