Problem: A power plant is looking to implement a flue gas desulfurization (FGD) system using Anhydrite. Explain how Anhydrite will help reduce sulfur dioxide (SO2) emissions and the environmental benefits of this approach. Additionally, mention any potential challenges that might arise in this implementation.
Anhydrite reacts with sulfur dioxide (SO2) in the presence of water to form gypsum (CaSO4·2H2O). This reaction removes SO2 from the flue gas, significantly reducing emissions. This process is crucial for mitigating acid rain, improving air quality, and reducing respiratory problems associated with SO2 pollution.
The use of Anhydrite in FGD systems offers several environmental benefits:
Potential challenges that might arise during implementation include:
