USEPA’s recent promulgation of the Clean Air Interstate Rule (CAIR) and Clean Air Mercury Rule (CAMR), and the designation of domestic fine particulate non-attainment areas, has spurred interest in adding particulate matter (PM) and mercury continuous emission monitoring systems (CEMS) to US power plants. While much of this interest has centered at least initially on pulverized coal-fired boiler units, the burgeoning integrated gasification combined cycle (IGCC) power market will likely also face the challenge of applying these new air emission measurement technologies. This paper will address the regulatory drivers which will encourage application of the PM and mercury CEMS on IGCC facilities, and it will discuss and evaluate the various measurement technologies/equipment available to comply with the new continuous emission measurement requirements. It will also summarize how various monitoring equipment suppliers have responded to this regulatory initiative. Finally, it will offer strategies to reduce the attendant risks and uncertainties associated with applying what are essentially emerging measurement technologies — technologies that will be tasked with demonstrating compliance with well-defined, strict air emission limitations.
