Question
Suggest two reasons why the sulfur dioxide by-product of this process is removed from the exhaust gases.
Solution
-
Environmental Protection
The removal of sulfur dioxide (SO₂) from exhaust gases is crucial for environmental protection. Sulfur dioxide is a significant contributor to acid rain, which can lead to severe environmental damage, harming ecosystems, aquatic life, and vegetation. By eliminating SO₂ from emissions, industries help reduce the overall acidification of soil and water bodies, thus mitigating its harmful impact on the natural environment.
-
Human Health Concerns
Sulfur dioxide is also a harmful pollutant that poses risks to human health. Exposure to SO₂ can irritate the respiratory system, leading to symptoms such as coughing, throat irritation, and aggravated asthma. Removing sulfur dioxide from exhaust gases helps improve air quality, thereby protecting public health and preventing respiratory diseases among populations living near industrial areas or heavily trafficked roads.
