Brandon Shores Air Quality Control Retrofit
Constellation Energy undertook a multi-year air quality control system project prior to new regulatory requirements from the Maryland Healthy Air Act. At more than 1,300-megawatts of capacity, the Brandon Shores project represents one of the largest air quality control retrofits in the United States. We were hired as Owner's Engineer for the project in 2006, kicking off a four-year involvement executed under a target cost engineer, procure, and construct (EPC) contracting structure.
Project considerations were to remove up to 95 percent of the sulfur dioxide emissions and 90 percent of the mercury emissions. Project support included installation of both hydrated lime injection for sulfur dioxide control and PAC injection for mercury control as well as pulse jet fabric filters. A wet flue gas desulfurization system diverts flue gases from old chimneys to a new, 400-foot high wet chimney.
Constellation Energy put Brandon Shores in compliance with the new regulatory requirements before they took effect. Initial testing showed the systems exceeding expectations for control of air pollutants.
