Desulphurization of SO2–N2 mixtures by limestone slurries
Olausson et al. (1993) developed a model for the removal of SO 2 from flue gas by absorption into a limestone slurry within a desulphurization unit comprising an absorber tower and an oxidation tank. The absorption rates of SO 2 and CO 2 in the tower were calculated according to the two-film model. Particle size had a slight effect on the absorption capacity of the SO 2 in …
