SO2 scrubber is an air pollution control system designed to remove sulfur dioxide (SO2) emissions from industrial exhaust gases. It operates using a chemical absorption process, typically involving an alkaline scrubbing solution like limestone (CaCO3) or sodium hydroxide (NaOH), which reacts with SO2 to form harmless by products such as gypsum or sodium sulfite. SO2 scrubbers are widely used in power plants, refineries, chemical processing, and metal smelting industries to reduce acid rain-causing emissions. sulfur dioxide, these scrubbers help industries comply with environmental regulations, protect air quality, prevent equipment corrosion, and promote cleaner, more sustainable operations.
