Portland cement industry PM{sub 2.5} and PM{sub 10} emission testing
The Portland Cement Association and its member companies have undertaken a study of PM{sub 2.5} and PM{sub 10} particulate emissions from cement plants to compile accurate emission factor data and chemical characterization data. The scope of the testing for the cement manufacturing sources includes cement kilns, alkali bypass streams, clinker coolers, finish mills, raw mills, coal mills, silos, bagging operations, and loadout operations. To ensure consistency of the data, a recently developed PCA emission test protocol is being used at the plants participating in the program. This protocol was developed for PCA by Air Control Techniques, P.C. based on draft EPA PM{sub 2.5} test procedures released in 1989. The testing procedure specified in the PCA Protocol was developed because the US EPA has not yet promulgated a PM{sub 2.5} emission test reference method for stationary sources. The PM{sub 2.5} and PM{sub 10} data are being obtained simultaneously using a dual cyclone sampling train operated in a manner consistent with US EPA Method 201A. The sampling times are selected to ensure that there are adequate particulate catch weights in each particulate size category to allow for chemical analyses. The particulate samples are being analyzed for sulfates, nitrates, and ammonium compounds. The measured emissions of filterable PM{sub 2.5} were very low. The preliminary results of tests conducted at five cement plants indicate that the emissions of filterable PM{sub 10} are approximately sixteen percent (16%) of the value of the limited PM{sub 10} emission factor data published in the Fifth Edition of AP-42, Section 11.6. The air emission test data compiled from 1997 to 1999 for the PCA test program represent the most accurate and complete analyses of Portland cement industry particulate emissions that are presently available. These data will be helpful in the development of PM{sub 2.5} implementation programs.
