Description:
The report gives results of sampling and analysis to characterize and quantify particulate, organic, and inorganic chemical emissions in effluents from a totally sealed metallurgical furnace at a ferroalloy plant. Effluents were sampled downstream of a venturi scrubber during silicomanganese production (Test I) and upstream of the scrubber during ferromanganese production (Test II). Sampling and analysis methodology was essentially that of EPA's Level 1 Environmental Assessment procedure, supplemented by a specific analysis of polynuclear aromatic hydrocarbons (PAH). Good agreement was observed between the results of Level 1 organic analysis and the specific analysis of PAH. Good agreement was also found between the atomic absorption and spark source mass spectroscopic analyses of As and Sb. Because the tests involved different ferroalloy production processes, their results are not a quantitative measure of venturi scrubber efficiency. However, the data imply good particulate removal efficiency. The venturi scrubber also appears to be effective for removal of polynuclear aromatics, especially species in the higher molecular weight range.
