Effluents containing particulate and gaseous emissions are exhausted from certain processes of the secondary zinc industry. Data on those emissions with related emission-control and process data were obtained from a sampling of plants. These data were evaluated to obtain the results of this study. Emissions from sweat processes occur at very low rates where the processed zinc scrap contains only small amounts of impurities. However, very significant emissions of particulate and gaseous carbonaceous substances, and particulate zinc oxide and zinc chloride may occur when there are substantial amounts of impurities in the scrap. The results of this study indicate that emission factors for zinc sweat processes range from zero to around 32 pounds of particulate per ton of scrap material processed. The results further indicate that the emitted particulate may be composed of zero to 34 percent ZnCl2; 40 to 100 percent ZnO; and small percentages of carbonaceous substance. Several emission-control concepts were developed based on findings of the study, and recommendations are made for further research and development. (Author)
