Detroit Edison upgrades pollution controls at Monroe plant

metromode, 11/19/2009

The Monroe Power Plant is becoming a bit cleaner these days now that Detroit Edison has installed a new pollution scrubber in the coal-fired power plant.

This is the second flue gas desulfurization system installed this year. It reduces sulfur dioxide emissions by about 97 percent and mercury emissions by 80-90 percent on the plant's No. 3 generating unit. The No 4. unit has a similar system that went into operation in June. The plant has four generating units.

Detroit Edison, a subsidiary of Detroit-based DTE Energy, has also installed other pollution control devices in recent years, including selective catalytic reduction systems on three of the plant's generating units to reduce nitrogen oxide output by 90 percent.

The Monroe facility is the first power plant in Michigan to install both of these systems. Installation on the remaining generating units is expected to begin next year. The scrubbers and catalytic reduction devices are expected to help the plant meet federal and state emission limits.
