| Abstract |
The report gives results of sampling and analysis of uncontrolled emissions from a Q-BOP, a bottom-blown Basic Oxygen Process for steelmaking, undertaken to characterize and quantify the particulate, organic, and inorganic species emitted during hot metal addition to precharged scrap metal. Sampling was in the secondary emission collection system before the emission control equipment and was conducted using EPA Level 1 Environmental Assessment Methodology. Particulate concentration was 1298 mg/cu m and total organic emissions were 64.1 mg/cu m. About 75% of this material was high molecular weight organics. The less than 3 micrometer solids contain over half of all the organics emitted. Although the presence of several carcinogenic polycyclic organic compounds was suggested by the LRMS analysis, GC-MS analysis showed that no known carcinogenic compounds were in the emissions. SSMS analysis indicated that eight elements might exceed Air-Health MATE values if emitted uncontrolled. Calculated control levels needed range from 63 to 99.6%. |
