A model of a DME fuel production plant was designed and analyzed in Aspen Plus. The plant produces DME by catalytic conversion of a syngas generated by gasification of torrefied woody biomass. Torrefication is a mild pyrolysis process that takes place at 200-300°C. Torrefied biomass has properties similar to coal, which enables the use of commercially available coal gasification processing equipment. The DME plant model is integrated with a steam cycle that utilizes waste heat from the plant and covers the on-site electricity consumption. The plant model predicts a fuel production efficiency of 67 % (LHV) from torrefied biomass to DME and 70 % (LHV) if the exported electricity is included. When accounting for raw, untreated biomass, the efficiency for DME production is reduced to about 60 %
