X-Ray Fluorescence-Based Multi-Metal Continuous Emission Monitor: Development
Abstract
Army demilitarization incinerators will need to comply with the Hazardous Waste Combustor National Emission Standards 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 types and quantities of emitted metals. Compliance may be determined only through trial burn emission tests because of this limitation. 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. The XCEM multi-metal CEM was developed using x-ray fluorescence (XRF) as the analytical method and an automated sampling system that provides extractive batch sampling onto a filter tape. The system is operated with user-friendly WonderWare software that provides automation, calibration routines, and report generation. A prototype XCEM was tested in the laboratory with a spiked gas stream against U.S. Environmental Protection Agency Reference Method 29 for four sample runs. The XCEM met the relative accuracy criteria for four of seven metals. A field-ready XCEM was built for demonstration at the 1236 Deactivation Furnace at Tooele Army Depot, Utah.
