摘要:An emission factor is a tool that is used to estimate air pollutant
emissions to the atmosphere. It relates the quantity of pollutants released from
a source to some activities associated with those emissions. To determine the
quantity of pollutant released from copper and its alloys smelting furnaces, 63
samples from emission gases were collected on cellulose ester membrane filters
in three 8-hour-shifts within 24 hours during a week at three locations. Samples
were weighed and analyzed to measure the heavy metal content by flame atomic
absorption spectrometry. The emission factors for location 1, without control
equipment, for total particulate matter (TPM), Cu, Zn, Pb, Cr, Ni, and Cd were
87.689, 2.076, 37.071, 0.917, 0.023, 0.074, and 0.021 g/Mg of products
respectively. Emission factors for location 3, with dedusting unit as control
equipment, were 8.139, 0.152, 3.921, 0.055, 0.003, 0.008, and 0.007 g/Mg for the
above-mentioned parameters respectively. Finally those were 95.828, 2.228,
40.992, 0.972, 0.026, 0.082, and 0.028 g/Mg as a whole set respectively. Samples
of location 2 were collected from inlet of dedusting unit and their results were
used only for dedusting unit efficiency calculation.
