A scrubber in the exhaust of a chemical industrial plant removes:
Correct answer: A. Gases like sulphur dioxide.
- A. Gases like sulphur dioxide.
- B. Particulate matter of the size 5 micrometer or above.
- C. Gases like ozone and methane.
- D. Particulate matter of the size 2.5 micrometer or less.
Explanation
Dust separation is carried out by scrubbers. They are of two types, dry and wet. Both can be used to separate particulate matter by passing through dry or wet packing material but more commonly they are employed in removing gaseous pollutants like SO2. Scrubbers are widely used to remove sulfur dioxide (SO2) pollutants from industrial emissions. SO2 is a major air pollutant that is primarily produced through the combustion of fossil fuels, such as coal and oil. It is a key contributor to air pollution and can have adverse effects on the environment and human health. Scrubbers, specifically designed for SO2 removal, help mitigate these impacts by capturing and neutralizing the SO2 emissions.
