METHOD FOR REMOVING CO2 FROM A SMOKE OR EXHAUST GAS OF A COMBUSTION PROCESS

摘要

The invention relates to the removal of CO2 from the smoke or exhaust gas (20) of a combustion process in a power plant (1). The exhaust gases comprising CO2 are fed into a tank (30) in which cellular organisms (40), such as micro algae, are present, converting the CO2 into biomass (10) when nutrients (N) are added. The micro algae and/or the generated biomass have magnetic particles (60) added, which combines with the algae and/or the biomass. The biomass having the magnetic particles is separated in a magnetic separation stage (120) or magnetic drum separator.
