Spray Dryer Absorber Power Plants

Spray Dryer Absorber (SDA) - Babcock & Wilcox

SDA systems are designed for utility boilers typically burning low to medium sulfur coals, smaller utility applications and combined HCl and SO 2 control on waste-to-energy units. B&W’s typical SDA system installations meet or exceed air quality regulations and operate at 90 to 95 percent SO 2 removal efficiency, with some plants running as high as 98 percent.

Spray Dryer Absorbers - Wheelabrator

The Amec Foster Wheeler, formally Wheelabrator, Spray Dryer Absorber (SDA) system is especially well suited to control SO2 and acid gas emissions. Our large utility and industrial fleet is installed at a wide range of facilities ranging from power plants, waste-to-energy plants, and hazardous waste plants. SDA designs can range from truck shippable industrial designs to larger absorbers ...

Scrubber - Wikipedia

Scrubber systems (e.g. stone scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams. The first air scrubber was designed to remove carbon dioxide from the air of an early submarine, the Ictineo I, a role for which they continue to be used today.
