Consider the following statements regarding Flue Gas Desulphurisation (FGD):
- FGD is primarily used to remove Sulphur Dioxide (SO₂) from flue gases generated by fossil fuel combustion, particularly coal.
- The process helps mitigate acid rain and particulate matter pollution, which adversely affect the environment and human health.
- Common reagents used in FGD systems include limestone (CaCO₃), lime (CaO), and ammonia (NH₃) to neutralise SO₂.
Which of the statements given above are correct?
Explanation:
Flue Gas Desulphurisation (FGD) is a critical pollution-control process for removing Sulphur Dioxide (SO₂) from flue gases produced by fossil fuel combustion—especially coal. This reduces SO₂ emissions, a major contributor to acid rain and particulate pollution, which harm ecosystems, infrastructure, and human health. The process typically uses reagents like limestone (CaCO₃), lime (CaO), or ammonia (NH₃) to neutralise the SO₂.
