What control device is the most effective for reducing sulphur dioxide pollution?

Scrubbers are highly effective control devices used for reducing sulfur dioxide (SO2) emissions in various industrial processes. They operate by utilizing a liquid solution, typically water mixed with alkaline substances, to capture and neutralize sulfur dioxide gas. When the flue gas containing SO2 passes through the scrubber, the gas interacts with the scrubbing liquid, leading to the conversion of the sulfur compounds into less harmful substances, such as sulfates, which can be efficiently removed from the gas stream.

The effectiveness of scrubbers lies in their appropriateness for handling gaseous pollutants like sulfur dioxide. They not only reduce emissions but can also often allow for the recovery of by-products, depending on the scrubbing material used. This makes them a versatile choice for environmental compliance and overall pollution control.
