Measurement of Sulfur Dioxide,Particulate,and Trace Elements in Copper Smelter Converter and Roaster/Reverberatory Gas Streams.

摘要

The report gives the results of the analysis of data on particulate,sulfur dioxide (SO2),and trace element emissions and control efficiencies for a copper smelter. The SO2emission rates from the roaster/reverberatory and converter effluent streams were 518and 587lb/min,respectively. The acid plant's SO2control efficiencym was 96.8percent. The mass collection efficiency of the converter's electrostatic precipitator (ESP) for dry filterable solids was 95percent. Analyzing emitted particulate gave the following mass emission rates (in lb/hr) for selected elements:arsenic (58.05),lead (24.65),cadmium (1.32),zinc (15.7),chromium (0.065),and copper (4.825). Control efficiency for the analyzed elements was between 90and 98percent.
