Techno-economic and environmental analysis of methanol and dimethyl ether production from syngas in a kraft pulp process

François Maréchal, Daniel Alexander Florez Orrego

The conventional configuration of a pulp mill, in which black liquor is concentrated and burnt, is compared to the upgrading gasification routes for methanol (MeOH) or dimethyl ether (DME) co-production. To this end, various exergy-based and environmental ...
