Key principles and approachesin wet-limestone scrubbing

Sulphur dioxide is first absorbed into the liquid phase as it contacts the slurry sprays. SO 2 + H 2 O <=> H 2 SO 3. Some theoretical chemists argue that true H 2 SO 3 does not exist and that SO 2 retains its molecular character and is surrounded by water molecules. However, when SO 2 is added to water the pH drops, which suggests this …
