Biomass-based carbon capture and utilization in kraft …

4/1/2019 · Kraft pulp mills produce CO 2 mainly in combustion processes. The largest sources are the recovery boiler, the biomass boiler, and the lime kiln. Due to utilizing mostly biomass-based fuels, the CO 2 is largely biogenic. Capture and storage of CO 2 (CCS) could offer pulp and paper industry the possibility to act as site for negative CO 2 emissions.
