A scrubber in the exhaust of a chemical industrial plant removes
Updated On: Jul 12, 2022
- Gases like ozone or methane
- Gases like Sulphur dioxide
- Gases like Nitrous oxide
- Particulate matter of the size 5 micrometers or above
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
A scrubber can remove gases like sulphur dioxide. In a scrubber, the exhaust is passed through a spray of water or lime water. Water dissolves gases. The particles also become heavy and fall down. Lime reacts with sulphur dioxide to produce a precipitate of calcium sulphate or sulphite, used to remove soluble gases and particles.
