Abstract

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 (NO₂‎), and sulfur dioxide (SO₂)) 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 NO₂ concentrations were detected in 2020 and 2016 followed by 2017 respectively, where NO₂ is positively correlated with DSS and negatively correlated with TDF and varies with diesel, coal, and RDF. Moreover, the maximum concentrations of SO₂ 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.

评估水泥工业中使用的不同燃料对污染物排放和环境空气质量的影响:埃及案例研究

本研究旨在利用AERMOD分散模型评估2014-2020年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(TSP)、二氧化氮(NO2)和二氧化硫(SO2))排放和浓度的影响及其对环境空气质量的影响。结果表明，在2015-2020年将燃料从2014年的天然气转变为煤炭混合替代燃料(轮胎衍生燃料(TDF)、干污泥(DSS)和垃圾衍生燃料(RDF))会导致污染物排放和浓度的波动变化。TSP浓度最大值和最小最大值分别出现在2017年和2014年，其中TSP与煤、RDF和DSS呈正相关，与天然气、柴油和TDF呈负相关。此外，NO2浓度最低和最高分别出现在2020年和2016年，其次是2017年，其中NO2与DSS呈正相关，与TDF负相关，并随柴油、煤炭和RDF变化。SO2的最大浓度在2018年最低，在2016年最高，其次是2017年，因为SO2与天然气和DSS呈显著正相关，与RDF、TDF和煤炭呈显著负相关。总的来说，增加TDF和RDF的比例，降低DSS、柴油和煤炭的比例，可以减少污染物的排放和浓度，改善环境空气质量。
