TL;DRAbstract

In a pulp mill the energy conversion mainly takes place in a recovery boiler that is fuelled with black liquor. The recovery boiler is also part of the facility that regenerates the chemicals at the pulp mill. The purpose of this work is to investigate the technical performance and cost when capturing CO2 from the flue gases from the recovery boiler. In order to broaden the analysis different supplementary fuels have been used to satisfy the increased energy demand due to the CO2 capture. The aim with the project is to evaluate whether or not capturing the CO2 from the exhaust gases in the recover boiler is a cost effective way of reducing the CO2 emissions.
