Wet-Limestone Scrubbing Fundamentals | Power …
Wet-limestone scrubbing is a classic example of an acid-base chemistry reaction applied on a large industrial scale. Simply stated, an alkaline limestone slurry reacts with acidic sulfur dioxide.
Scrubber - Wikipedia
Scrubber systems (e.g. stone scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used today.

Wet lime scrubbing | EMIS
Originally, the process was made up of two absorbers and an oxidation unit. SO 2 and limestone are absorbed in the absorber, whereby calcium sulphite is created. In the oxidation barrel under the absorber, this is then converted into dihydrate gypsum, CaSO 4 .2H 2 O, at a relatively low pH (5.5 - 6).
