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 ...

Diformylxylose as a new polar aprotic solvent produced from renewable biomass

Jeremy Luterbacher, Anastasiia Komarova, Graham Reid Dick

Lignin is a promising candidate for the replacement of fossil-based materials, due to its natural abundance and aromatic structure. This same structure poses major challenges to lignin's exploitation for material development. The harsh conditions generally ...

A dual representation for targeting process retrofit, application to a pulp and paper process

François Maréchal, David Brown

A method for the analysis of process energy requirements has been used to identify in an early design stage the potential process retrofit measures in an integrated pulp and paper mill. The minimum energy requirements (MER) of the process were computed by ...
