A bubble column reactor was tested and evaluated for carbon dioxide removal from flue gases by using magnesium hydroxide slurry. The study showed that a high CO₂ removal efficiency could be achieved. An absorption model was developed for system analysis and CO₂ removal data analysis. The overall mass transfer coefficients for CO₂-H₂O and CO₂-Mg(OH)₂-H₂O systems have been calculated. The chemistry of the system, temperature effects, and changes of equilibrium constants also have been discussed.
