Integration of biomass gasification with a Scandinavian
Highlights Biomass gasification integrated with a TMP mill has been examined. Consequences for mass and energy balances, and CO 2 emissions, have been evaluated. Three cases have been evaluated: production of electricity, methanol and FT liquid. A TMP mill can steadily utilize the excess heat from the gasification process. Integrated gasification results in lower CO 2 emissions than stand
