X-Ray Fluorescence-Based Multi-Metal Continuous Emission Monitor
ABSTRACT: Army demilitarization incinerators will need to comply with the Hazardous Waste Combustor National Emission Standard for Hazardous Air Pollutants that will regulate metals and metal compounds listed under the Clean Air Act Amendments. A large problem for these incinerator operations is limited knowledge of the type and quantity of emitted metals, so that compliance may be determined only through trial burn emission tests. A continuous emission monitor (CEM) for multi-metals will provide the emission data, a tool to help meet compliance requirements, and the opportunity to adjust burn strategies for increased production. A user-friendly multi-metal
CEM that uses x-ray fluorescence (XRF) as the analytical method and an automated sampling system that provides extractive batch sampling onto a filter tape (XCEM) was demonstrated at the 1236 Deactivation Furnace at Tooele Army Depot, Utah. The unit was compared to EPA Reference Method 29 during two separate tests (2001 and 2002). The second test was performed after improvements were made to the sample transport and system calibrations. The results indicate that the XCEM has met the proposed Performance Specification 10 for multi-metal CEMs except for relative accuracy requirements for 4 of 9 metals. Its failures are attributed mostly to inadequacies in the reference method. The monitor is proving useful at Tooele and is ready for implementation at other Army demilitarization incinerators.
