Measurements of Mercury Released from Amalgams and Sulfide Compounds

Description: This report covers work performed during FY 1998 in support of treatment demonstrations conducted for the Mercury Working Group. In order to comply with the requirements of the Resource Conservation and Recovery Act, as implemented by the US Environmental Protection Agency (EPA), the US Department of Energy (DOE) must apply amalgamation, the treatment standard for radioactively contaminated mercury, before disposing of these wastes. The Mercury Working Group under the Mixed Waste Focus Area spo… more

Studies of Mercury in High Level Waste Systems

Description: Historically, mercury was added to the nuclear weapons processing as a catalyst for the dissolution of aluminum metal. After neutralization the mercury was disposed to the High Level Waste tanks where its speciation led to mercuric oxides/hydroxides in the sludge and a small soluble mercuric ion concentration in the alkaline supernate. This report in its original revision described a three-pronged approach for studying possible sources of elevated mercury vapor in and around the Tank Farm evapo… more

Avoiding Carbon Bed Hot Spots in Thermal Process Off-Gas Systems

Description: Mercury has had various uses in nuclear fuel reprocessing and other nuclear processes, and so is often present in radioactive and mixed (radioactive and hazardous) wastes. Test programs performed in recent years have shown that mercury in off-gas streams from processes that treat radioactive wastes can be controlled using fixed beds of activated sulfur-impregnated carbon, to levels low enough to comply with air emission regulations such as the Hazardous Waste Combustor (HWC) Maximum Achievable … more

OFF-GAS MERCURY CONTROL USING SULFUR-IMPREGNATED ACTIVATED CARBON – TEST RESULTS

Description: Several laboratory and pilot-scale tests since the year 2000 have included demonstrations of off-gas mercury control using fixed bed, sulfur-impregnated activated carbon. These demonstrations have included operation of carbon beds with gas streams containing a wide range of mercury and other gas species concentrations representing off-gas from several U.S. Department of Energy (DOE) mixed waste treatment processes including electrical resistance heated (joule-heated) glass melters, fluidized be… more
