As sulfur dioxide is an ,acidic, gas it will need to be neutralised before disposal. To do this an alkaline-based sorbent is used to bring the pH level of the sulfur dioxide gas closer to neutral. Scrubber systems are one of the most efficient ways of reducing sulfur dioxide emissions caused by industrial combustion, and a classic example of an acid-base chemical reaction performed on an industrial scale.
