Enhancing the recovery of gypsum in limestone-based wet …

Commercial experience has shown that fresh slurry pH as it enters the absorber should be in the range 5.5–6.0 for limestone systems (Wang et al., 2005). As the SO 2 is absorbed from the flue gas, the slurry becomes more acidic and the pH drops. The pH of the spent slurry as it leaves the absorber is in the range 4.0–5.0 for limestone …
