Abstract
This thesis aimed to assess the level of pollutant concentrations resulting from a cement factory and predict their dispersion in the surrounding area. The study focused on four pollutants: PM10, CO, NOx, and SOx. The Breeze AERMOD modeling program was utilized to simulate and predict the dispersion of these pollutants within a 20-kilometer diameter of the Helwan cement plant.
The results of the dispersion modeling revealed significant levels of pollutant concentrations in the vicinity of the cement plant. The average concentration of PM10 over 24 hrs was found to be 182 micrograms per cubic meter (µg/m³), exceeding the permissible limit of 150 µg/m³ set by the environmental regulations. This indicates a potential risk to respiratory health for the communities living near the cement plant.
The concentrations of NOx, and SOx were also found to exceed the recommended limits. The average concentration of of NOx and SOx over 1 hr were recorded at 212 ppm and 302ppm, respectively, exceeding the allowable limits of 180 ppm and 300 ppm. These elevated levels of pollutant concentrations indicate the potential for adverse respiratory and cardiovascular effects among the local population.
The comparison of the obtained results with applicable regulations for ambient air quality emphasized the need for immediate action to mitigate the emission of pollutants from the cement plant. The findings underscored the importance of implementing stricter emission control measures, investing in cleaner technologies, and adopting sustainable practices in the cement industry.
The research highlighted the significance of addressing the environmental and health implications of cement plant emissions. The high concentrations of pollutants in the surrounding area indicate the urgent need for collaborative efforts between policymakers, industry stakeholders, and environmental agencies to develop and enforce effective strategies for reducing emissions and improving air quality.
To achieve this, the cement industry should consider implementing measures such as installing advanced air pollution control systems, optimizing fuel combustion processes, and exploring alternative cleaner energy sources. Regular monitoring and reporting of emissions should be conducted to ensure compliance with environmental regulations.
In conclusion, this thesis provides valuable insights into the environmental and health impacts of cement plant emissions. The results demonstrate the urgent need for proactive measures to mitigate the adverse effects of air pollution on nearby communities. By implementing comprehensive emission reduction strategies, the cement industry can contribute to safeguarding public health and minimizing the environmental footprint of its operations.
