McDermott International Inc. has announced that one of its subsidiaries, Babcock & Wilcox Power Generation Group Inc. (B&W), has signed a contract worth approximately USD 90 million to design, engineer, procure and construct wet flue gas desulfurization (FGD) systems, commonly called scrubbers, for two 825MW units at Detroit Edison Co.’s Monroe Power Plant in Monroe, Michigan, US. B&W’s full scope of supply includes the absorber island, piping, outlet flues and other associated equipment. B&W also designed and installed scrubbers for the control of sulfur dioxide emissions on the Monroe plant’s two other units, which began operation in 2009. The B&W contract is a component of Detroit Edison’s overall FGD project, which is estimated to cost about USD 600 million and includes construction of a new 580ft chimney, a building to house the absorber system, installation of control systems and construction of additional infrastructure.
