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

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 ...

Exergy and environmental analysis of black liquor upgrading gasification in an integrated kraft pulp and ammonia production plant

Daniel Alexander Florez Orrego

The black liquor is a byproduct of the kraft pulping process that contains more than half of the exergy content in the total woody biomass fed to the digester, representing a key supply of renewable energy to the pulping process. In this work, the conventi ...

Exergy and environmental analysis of black liquor upgraded gasification in an integrated kraft pulp and ammonia production plant

Daniel Alexander Florez Orrego, Meire Ellen Gorete Ribeiro Domingos

Some byproducts of the Kraft pulp mills, such as the black liquor (1.4 t/t ADpulp, 15% solids), still contain more than half of the exergy content of the total wood fed to the digester. This residue represents a key supply of renewable energy to the pulp a ...
