Biofuels are generally regarded as a valid replacement for crude oil derivates, as they have the potential to provide environmental sustainability, carbon neutrality, and energy security through diversification of supply. In this work, industrial-scale bio-fuel production was designed and simulated using Aspen Plus process simulation software. Experimental data for bench scale indirectly heated pyrolysis of brown alga Saccharina japonica was used. Process design includes pretreatment of the “as is” seaweed feedstock, pyrolysis conversion, heat and power production via solid bio-char combustion and downstream processing of the liquid pyrolysis oils through quench phase separation and hydrotreatment. In this stage, the research provides a strong insight into a complete industrial process of bio-fuel production via pyrolysis, including mass and energy balances, as well as an initial economic assessment. Subsequent research will present viable process alternatives, different market scenarios and integration with a biochemical conversion platform. |
