ENGINEERING AND ECONOMIC FACTORS AFFECTING THE INSTALLATION OF CONTROL TECHNOLOGIES FOR MULTIPOLLUTANT STRATEGIES
Jozewicz, W. ENGINEERING AND ECONOMIC FACTORS AFFECTING THE INSTALLATION OF CONTROL TECHNOLOGIES FOR MULTIPOLLUTANT STRATEGIES. U.S. Environmental Protection Agency, Washington, DC, EPA-600/R-02/073, 2002.
The report evaluates the engineering and economic factors associated with installing air pollution control technologies to meet the requirements of strategies to control sulfur dioxide (SO2), oxides of nitrogen (NOX), and mercury under the Clear Skies Act multipollutant control strategies. The control technologies considered by the report as candidates to be used for multipollutant control strategies include limestone forced oxidation (LSFO) flue gas desulfurization (FGD) for the control of SO2, selective catalytic reduction (SCR) for the control of NOX, and activated carbon injection (ACI) for the control of mercury.
The study found that the expected demand for resources resulting from a multipollutant control strategy could be met. Sufficient steel and general construction labor to support new installations now exist. There is also ample SCR catalyst capacity to supply the market, and an ample supply of limestone for additional FGD systems is currently available. The ammonia and urea supply is also plentiful because a worldwide excess production capacity of these commodity chemicals presently exists. Although U.S. demand for activated carbon is expected to increase by a small amount as a result of a multipollutant strategy, there is currently a substantial excess global capacity of activated carbon production that can readily provide for this increase in demand.
