Market Summary
- The market is a critical segment of the global industrial emissions control industry, driven by stringent regulations aimed at reducing sulfur oxide emissions. FGD systems are essential for power plants and industrial processes that rely on fossil fuels, as they help mitigate the environmental impact of sulfur dioxide (SO2) emissions. One primary trend in the FGD market is the increasing preference for dry FGD technology. This technology offers several advantages over traditional wet FGD systems, including lower water consumption, reduced sludge generation, and improved operational efficiency. Dry FGD systems use sorbents like limestone or magnesium oxide to absorb SO2 directly from the flue gas stream, eliminating the need for water-based scrubbing.
- Another significant factor influencing the FGD market is the volatility in oil and gas prices. As fossil fuels are the primary feedstock for power generation and industrial processes, price fluctuations can significantly impact the economics of FGD system implementation. However, despite these challenges, companies continue to invest in FGD systems to ensure compliance with emissions regulations and improve operational efficiency. For instance, a large cement manufacturer in Europe implemented an FGD system to reduce its SO2 emissions and meet stringent European Union emissions standards. The system not only helped the company comply with regulations but also improved its overall energy efficiency by utilizing waste heat from the FGD process to generate electricity.
- This scenario underscores the importance of FGD systems in addressing environmental concerns while optimizing industrial processes.

The wet FGD segment is estimated to witness significant growth during the forecast period.
Wet Flue Gas Desulfurization (FGD) systems have gained significant traction due to their high sulfur removal efficiency, reaching up to 95%. In these systems, flue gases are washed with an aqueous solution of absorbent, typically limestone, leading to the formation of calcium sulfite or calcium sulfate. This process effectively reduces sulfur dioxide emissions, contributing to improved air quality and compliance with stringent emission standards. The regenerative process involves heating the absorbent to release the sulfur compounds, which are then converted back into the absorbent for reuse. Advancements in FGD technology include fluid dynamics modeling for optimizing process efficiency, automation systems for real-time monitoring and control, and data analytics for energy consumption and absorption efficiency analysis.
Wet FGD systems also offer heat recovery opportunities and can be integrated with wastewater treatment systems for effective water management. Despite the high initial investment, the long-term cost savings, including the sale of gypsum byproduct, make FGD systems a sound investment. For instance, the global FGD market is projected to reach a value of USD16.8 billion by 2026, growing at a compound annual growth rate of 5.3%. This growth is driven by the increasing focus on reducing stack emissions and the evolving regulatory landscape.
The Wet FGD segment was valued at USD 9.5 billion in 2019 and showed a gradual increase during the forecast period.
