In last years the production of biofuels has generated a high interest because of governments’ actions to reduce fossil fuels consumption in transport and other uses. The aim of this work is the economic analysis of the co­production of synthetic natural gas (SNG) and bioethanol in a biorefinery context. Conceptual process design and techno­economic assessment of a plant size of 2140 dry tonne/day of wood chip (500 MWth) is presented. The proposed Bio SNG­Ethanol process...
