The black liquor gasification integrated to chemical plants has shown potential for reducing the process irreversibility and promoting decarbonization of this industrial sector. In proposed in work, purpose is co-producing pulp gaseous fuels, either hydrogen or synthetic natural gas, order expand biorefinery product portfolio and, consequently, increase plant revenues. However, due additional equipment utility demands, along with uncertainty about prices commodities; benefits setups must be thoroughly weighed by considering thermodynamic, economic environmental indicators before retrofit existing configuration implemented. exergy method used energy integration technique other financial determine whether which scenarios biorefineries would more attractive. average efficiency production 44%, higher than that conventional case (40%). balance overall CO2 emissions vary from 1.97 −0.56 tCO2/tPulp, setups, respectively. An incremental analysis under also shows route partial import electricity carbon taxations above 60 EUR/tCO2 outperforms scenarios. Therefore, low-carbon grids upgrade residues arise as key factors ensuring sustainable traditionally fossil-based chemicals stringent regulations.

Inorganic Chemistry during Pyrolysis, Gasification, and Oxyfuel Combustion of Kraft Pulping Black Liquor

Energy & Fuels, Год журнала: 2024, Номер 38(6), С. 5279 - 5287

Changed utilization of black liquor in the pulp and paper industry has potential to offer simplified carbon capture and, thus, negative net emissions from these large point sources. This can be achieved either by adapting existing recovery boilers oxyfuel combustion or replacing them with gasification technology. In this work, chemistry during conversion was therefore studied detail under different atmospheres relevant for pyrolysis, gasification, combustion. Experiments were performed using environmental scanning transmission electron microscopy (ESTEM) thermogravimetric analysis (TGA), supported thermodynamic equilibrium calculations (TECs) understand interpret results. Black found generally similar air containing approximately 20–25 mol % oxygen. The results however indicated that there a higher probability forming carbonates melt at dioxide (CO2) partial pressures, which addition associated potentially sulfur loss conversion. Both characteristics negatively affect chemical recycling mill increasing need lime makeup chemicals.
