Air pollution causes significant environmental and health problems around the world. The present study assesses the emission of CO, SO2, and NOX from six sugarcane factories (SCFs) in Egypt, which are using two dominant fuels, bagasse and natural gas. The detected CO emission and concentrations levels from the stacks of SCFs that used bagasse were higher (1751–3030 mg/Nm3) than those using a mixture of bagasse and natural gas (555 mg/Nm3), as well as natural gas only (169.2–246.5 mg/Nm3). The emission of CO is higher than permissible levels, but SO2 (2.5–26.5 mg/Nm3) and NOX (25.5–149.75 mg/Nm3) emissions in all kinds of fuels are within the permissible levels. Dispersion of CO in the ambient from stack emission from Kom Ombo SCF is simulated using the Ministry of Economic, Trade, and Industry Low-Rise Industrial Source dispersion (METI-LIS) model. The results predicted the higher risk zone (>10 ppmv) extends ~1 km around the KSCF and occupies the near middle part of the plume, but the lower zone (<0.1 ppmv) occupies the outer zone and extends for several kilometers. Measurements in the ambient air validated the predicted model, which revealed that people living in areas about 1 km south and west downwind of the KSCF are exposed to higher levels of CO concentration. Usage of bagasse in SCFs needs to be replaced by natural gas for the reduction in emission of pollutants. Moreover, pollutants emitted from the SCFs should be monitored periodically to control the emission for healthy environment.

评估埃及甘蔗工厂的CO,SO 2和NO X排放,并预测CO浓度的潜在区域

空气污染在世界范围内引起严重的环境和健康问题。本研究评估了埃及六家甘蔗工厂(SCF)的CO,SO 2和NO X排放,这些工厂使用两种主要燃料,甘蔗渣和天然气。与使用蔗渣和天然气的混合物(555 mg / Nm 3)以及仅使用天然气的蔗渣相比,使用蔗渣的SCF堆栈中检测到的CO排放和浓度水平更高(1751–3030 mg / Nm 3)。(169.2–246.5 mg / Nm 3)。CO的排放量高于允许的水平,但SO 2(2.5–26.5 mg / Nm 3)和NO X(25.5–149.75 mg / Nm 3)各种燃料的排放均在允许的水平之内。使用经济,贸易和工业部的低层工业源扩散(METI-LIS)模型模拟​​了Kom Ombo SCF烟囱排放产生的环境中CO的扩散。结果预测,较高风险区(> 10 ppmv)围绕KSCF延伸约1 km,并位于羽流的中部附近,而较低风险区(<0.1 ppmv)则占外部区域并延伸数公里。对环境空气的测量验证了该预测模型,该模型表明,居住在堪萨斯州南部和西南偏风约1公里处的人们暴露于较高的CO浓度水平。为了减少污染物的排放,需要将SCF中蔗渣的使用替换为天然气。此外,
