Article 2: Flue Gas Desulphurization (FGD) Introduction: Flue Gas Desulphurization (FGD) is a critical technology in the effort to reduce air pollution from coal-fired power plants. The Ministry of Environment, Forest & Climate Change has made the installation of FGD systems mandatory for all coal-based Thermal Power Plants (TPPs). Understanding FGD technology and its implications is important for UPSC exam preparation, particularly in the context of environmental policies and pollution control. This article provides a comprehensive overview of FGD. About: Flue Gas Desulphurization (FGD) systems are designed to remove sulfur dioxide (SO2) from the flue gas emissions of coal-fired Thermal Power Plants (TPPs). These systems can remove over 90% of the SO2, significantly reducing air pollution. There are three major types of FGD systems: Dry Sorbent (Limestone) Injection, Wet Limestone Based, and Sea Water Based. Key Points: FGD systems remove over 90% of SO2 emissions from coal-fired TPPs. The Ministry of Environment, Forest & Climate Change has mandated FGD installation in all coal-based TPPs. Major FGD systems include Dry Sorbent (Limestone) Injection, Wet Limestone Based, and Sea Water Based. SO2 is a colorless, reactive air pollutant with a strong odor. High concentrations of SO2 can lead to the formation of other Sulfur Oxides (SOx). SOx contributes to particulate matter (PM) pollution. SO2 irritates the skin and mucous membranes of the respiratory system. SOx and Nitrogen oxides contribute to acid rain. SO2 emissions come from fossil fuel combustion and volcanic activity. Recent: Ministry of Environment, Forest & Climate Change mandates FGD installation. Recent Developments: The recent mandate by the Ministry of Environment, Forest & Climate Change for all coal-based TPPs to install FGD systems is a significant step towards controlling SO2 emissions. This reflects the government’s commitment to improving air quality and mitigating the environmental impact of coal-fired power generation. Impact: The widespread adoption of FGD technology will have several positive impacts: Reduced SO2 Emissions: Leading to cleaner air and improved public health. Decreased Acid Rain: Protecting ecosystems and infrastructure from the harmful effects of acid rain. Improved Air Quality: Contributing to the reduction of particulate matter pollution and associated health problems. Challenges: Cost of Installation: The high cost of installing FGD systems can be a barrier, especially for older power plants. Operational Costs: FGD systems require ongoing operational costs, including the cost of sorbents and waste disposal. Way Forward: Financial Assistance: Providing financial incentives or subsidies to help power plants cover the costs of FGD installation. Technology Development: Investing in research and development to improve the efficiency and reduce the cost of FGD technologies.
