Mercury Reduction Projects
Weston Power Plant
Environmental Retrofits at WPS
A series of emission control projects have recently been completed at WPS coal-fueled power plants that are designed to meet stricter state and federal air quality regulatory programs.
Mercury Reduction Project Description
The projects consist of new equipment installed to handle and inject dry sorbent materials into the power plant's exhaust gas. The sorbents are made of powdered activated carbon that is specially sized and chemically-treated to capture mercury, acting like a mercury-absorbing sponge. The carbon sorbent is injected into the exhaust gases upstream of existing particulate matter control equipment so that it can be separated from the exhaust before the gases reach the chimney.
Pulliam Power Plant
The used carbon sorbent is collected and comingled with the fly ash, which is tested for suitability for beneficial reuse or landfill disposal. As the mercury is physically and chemically bound to the carbon sorbent it is prevented from reemitting to the air or water.
Expected mercury reduction is in the 60 to 85 percent range using the activated carbon injection system.
These projects will allow us to meet compliance targets according to Wisconsin Mercury Rule (NR446.)
