ADA Technologies, Inc., is developing a continuous emissions monitoring system that measures the concentrations of mercury and volatile mercury compounds in flue gas. These pollutant species are emitted from a number of industrial processes. The largest contributors of these emissions are coal and oil combustion, municipal waste combustion, medical waste combustion, and the thermal treatment of hazardous materials. It is difficult, time consuming, and expensive to measure mercury emissions using current, manual sampling test methods. Part of this difficulty lies in the fact that mercury is emitted from sources in several different forms, such as elemental mercury and mercuric chloride. The ADA analyzer measures these emissions in real time, thus providing a number of advantages over existing test methods: (1) it will provide a real-time measure of emission rates, (2) it will assure facility operators, regulators, and the public that emissions control systems are working at peak efficiency, and (3) it will provide information as to the nature of the emitted mercury (elemental mercury Or speciated compounds). This paper presents an overview of the CEM and describes features of key components of the monitoring system--the mercury detector, a mercury species converter. and the analyzer calibration system.
