HCl and Cl{sub 2} are among the 189 hazardous air pollutants (HAPs) identified by the 1990 Clean Air Act Amendments (CAAA). Consequently, there is a significant need to measure and control HCl. Sources of HCl that will be regulated under the CAAA include hazardous waste incinerators, coal-fired boilers and municipal solid waste incinerators (MSWs). Coal-fired utility boilers represent a significant source of HCl due to the total volume of effluent produced even though the steady state concentration of HCl is relatively low (50--100 ppm). Continuous monitors that are currently available for measuring HCl are either very expensive (e.g., FTIR instruments), are sensitive to the amount of water vapor in the sample, (e.g. gas filter correlation technique), or simply are not accurate. Under a Department of Energy contract, ADA Technologies has successfully developed a new technique for measuring gas-phase, chlorinated species that can be applied to the simultaneous measurement of HCl and Cl{sub 2} in flue gas. The continuous monitor instrument has several advantages such as: it is specific to Cl so it does not suffer from interferences caused by other flue gas constituents such as SO{sub X}, CO{sub X}, H{sub 2}O, and NO{sub X}; and the analyzer can measure both HCl and Cl{sub 2}. This paper will presents results of laboratory and field tests that demonstrate the ability of the instrument to detect low levels of HCl and Cl{sub 2} (1--100 ppm).
