Abstract
The integrated production of second generation biofuel at a sulphite mill, by ethanol fermentation of spent sulphite liquor (SSL), can be expanded by gasification-synthesis to produce synthetic fuels from bark residues available onsite. The potential contributions of such synthetic fuel production to economic and environmental performance of the integrated facility, in comparison to ethanol production that is accompanied by heat and power generation from bark, were determined. Thus, bark is used either for (i) direct heat and power generation via direct combustion in a high pressure boiler or a biomass integrated gasification and combined cycle (BIGCC) or, alternatively, for (ii) gasification-synthesis to produce either methanol or Fischer-Tropsch (FT) synthesis crude (syncrude). Techno-economic evaluations and calculations of the net greenhouse gas reduction (NGGRP) potential for all process scenarios were conducted on the basis of Aspen Plus⊙ simulations. Combining synthetic fuels production with SSL-fe...
