“Dispersion Modeling Study of the Cement Plant Emissions over Greater Cairo”

Abstract

This study presents predictions of air pollutants (dust) emitted from cement plant that(National. Helwan, Tourah, and Kattameya factories) constructed in Greater Cairo the capital of Egypt. To do that, use different type of data as cement factory emission "Egyptian Environmental Affairs Agency”, Metrology data "Egyptian Meteorological Authority" data were used during 2012. Different types of programs as The Gaussian air pollution "ISC3" to analysis the data of cement monitoring network, MM5 Model to give the metrology data, GIS to representation the relation between data from dispersion model and metrology data are used and applied different scenarios on this data to give largest percent of emission improvement. To improve the cement factories emissions different scenarios as: • Maintenance and exchange filter. (applied on Helwan and Tourah factories) • Relocation of factory. (applied on National factory)

Then it is represented: • Dispersion of PM10 emission from cement industry over Greater Cairo This work aims to monitor and assess the PM10 emissions from four cement factories located in the Greater Cairo (National, Helwan, Tourah and Kattameya).The emission characteristics, raw material composition and seasonal concentrations are given. The minimum average PM10 concentration was obtained for Tourah in summer (25.9mg/m3) while the highestaverage concentration was obtained in spring(54.5 mg/m3). The seasonal average of 1303 readings of the year 2012 for Tourah was 45.4 mg/m3. For Helwan factory, the minimum averagePM10 concentration was obtained for in summer (55.1 mg/m3) while the highest average concentration was obtained in spring (115.5 mg/m3). The seasonal average of 1033 readings of the year 2012 was 83.1 mg/m3. The minimum average PM10 concentration for National Factory was obtained also in summer (84.3 mg/m3) while the highest average concentration wasobtained in autumn (89.8 mg/m3). The seasonal average of 1010 readings of the year 2012 was87.6 mg/m3. The minimum average PM10 concentration for Katamyia factory was obtained alsoin summer (54.1 mg/m3) while the highest average concentration was obtained in spring (60.5mg/m3). The seasonal average of 609 readings of the year 2012 was 57.2 mg/m3
