This study aims to assess the impact of using different fuels in Egyptian Titan Alexandria Portland Cement Company on emissions and concentrations of pollutants (Total suspended particles (TSP), nitrogen dioxide (NO), and sulfur dioxide (SO)) and their influence on ambient air quality during the period 2014-2020 using AERMOD dispersion model. The results showed that changing the fuel from natural gas in 2014 to coal mixed with alternative fuels (Tire-Derived Fuel (TDF), Dried Sewage Sludge (DSS), and Refuse Derived Fuels (RDF)) in 2015-2020 caused fluctuating variations in pollutant emissions and concentrations. The highest and lowest maximum concentrations of TSP occurred in 2017 and 2014 respectively, where the TSP is positively correlated with coal, RDF, and DSS and negatively correlated with natural gas, diesel, and TDF. Also, the lowest and highest maximum NO concentrations were detected in 2020 and 2016 followed by 2017 respectively, where NO is positively correlated with DSS and negatively correlated with TDF and varies with diesel, coal, and RDF. Moreover, the maximum concentrations of SO were the lowest in 2018 and highest in 2016 followed by 2017 because of its considerable positive correlation with natural gas and DSS and negative correlation with RDF, TDF, and coal. Generally, it was found that increasing the percentage of TDF and RDF with decreasing the percentage of DSS, diesel, and coal will reduce pollutant emissions and concentrations and enhance ambient air quality.
本研究旨在利用AERMOD扩散模型评估埃及泰坦亚历山大波特兰水泥公司使用不同燃料对污染物(总悬浮颗粒物(TSP)、二氧化氮(NO)和二氧化硫(SO))排放及浓度的影响,以及它们在2014 - 2020年期间对环境空气质量的影响。结果表明,燃料从2014年的天然气改为2015 - 2020年的与替代燃料(轮胎衍生燃料(TDF)、干污泥(DSS)和垃圾衍生燃料(RDF))混合的煤炭,导致污染物排放和浓度出现波动变化。TSP的最高和最低最大浓度分别出现在2017年和2014年,其中TSP与煤炭、RDF和DSS呈正相关,与天然气、柴油和TDF呈负相关。此外,NO的最低和最高最大浓度分别在2020年和2016年检测到,其次是2017年,其中NO与DSS呈正相关,与TDF呈负相关,并随柴油、煤炭和RDF而变化。此外,由于SO与天然气和DSS有显著正相关,与RDF、TDF和煤炭有负相关,其最大浓度在2018年最低,在2016年最高,其次是2017年。总体而言,发现增加TDF和RDF的百分比,同时降低DSS、柴油和煤炭的百分比,将减少污染物排放和浓度,并改善环境空气质量。
