The FGD Market is growing around the world. India is installing its first wet limestone system. China leads the world in number of MW using wet FGD. Many of the FGD systems in the U.S. are more than 20 years old and are being upgraded or replaced. The technology is also being shaped by the need to remove other pollutants such as mercury.
In this regard McIlvaine has created a free website: Mercury Removal - Continuous Analyses
One of the benefits of this website is the exposure of developing nations to the benefits of FGD and mercury removal in one device.
There are now a variety of dry scrubbers to remove SO2. This is also covered in a new website Dry Scrubbing - Continuous Analyses
There is now a commercial alternative to removal of all pollutants with one device. This is covered in Hot Gas Filters - Continuous Analyses
Ceramic filters with embedded catalyst are preceded by DSI. High removal levels of SO2 are achieved simultaneously with NOx and particulate removal.
Most of the market for coal-fired power plant flue gas desulfurization (FGD) is served by wet limestone systems which produce wall board quality gypsum. However, dry scrubbers are starting to gain traction. There are a number of reasons:

• Concern about water usage particularly in arid areas in the U.S. and China
• Ability to scale systems up to 500 MW in a single module
• New methods of converting the flyash/gypsum mixture into salable by-products
• Saturation of the gypsum market
• Concerns about capturing other pollutants such as SO3
• Regulations which dictate minimal capital investment (U.S.)
