EVALUATION OF SAMPLING TECHNIQUES FOR ATMOSPHERIC EMISSIONS FROM SINTERING IN THE IRON AND STEEL INDUSTRY. U.S. Environmental Protection Agency, Washington, D.C., EPA/600/4-81/023.
Description:
Tests were conducted at two sintering plants of the Iron and Steel Industry to evaluate a test method under consideration by the U.S. Environmental Protection Agency. In field tests, four modified Method 5 sampling trains, operating simultaneously at a single point in the stack, yielded four samples per sampling run. Each sample was analyzed for front-half filterable particulates and back-half organic solvent extractables (OSE). In addition, the effects of filter and probe temperatures on filter collection efficiency, and the effects of sample handling, storage conditions, and recovery procedures on sampling results were studied. Temperature fluctuations from 65 - 120C (150 - 250F) did not significantly affect the particulate concentrations, nor did additional dessication greater than the conventional time period. Chromatographic experiments indicated that pH 7 was preferable for OSE extraction.
