Title: Environmental Impact of Khartoum North Thermal Power Station in Kafoury Neighborhood
Author: Ahmed, Amin Ahmed Eltayeb
Abstract: The impact of thermal power plants on the atmosphere is the most important environmental hazard which is ignored by most of the thermal power plants to reduce investment and production costs. Air pollutants of thermal power plants are monitored by considering Sulfur Dioxide (SO2), Nitrogen Oxides (NOx) and Particulate Matter (PM) as main polluting factors. This study has been dealt with oil-fuel thermal power plant and took Khartoum North Thermal Power Station (KNTPS) as a model with an objective to study its environmental impact on the atmosphere of neighboring residential area and on residents (Kafoury block 9, in Khartoum, Sudan). The study was taking place between August 2015 to August 2016. Firstly, atmospheric environment quality of KNTPS had been tested for SO2 and NO2 emissions, three sampling spots were chosen in the target area after determining the testing scope and factors. The appropriate air pollutant testing and analysis methods were used to analyze the collected samples using multicomponent analyzer. The results of SO2 emissions of KNTPS do not meet the Sudanese Ambient Air Quality Standards Maximum Allowable Limits (SAAQSMAL), the average SO2 concentration measured for one-hour exposure was 1.00 ppm, whereas SO2 emission standard limit is 0.17 ppm. NO2 emission measured values for one-hour exposure was 0.029 ppm, whereas NO2 emission standard limit is 0.022 ppm. According to KNTPS, no technical measure has been introduced to reduce NO2 emission because of high quality fuel used. The technical measure to reduce SO2 in KNTPS is Flue Gas Desulfurization Continuous Emissions Monitoring System is used only in unit three, but after testing it was found that SO2 emission does not meet the standards, and may cause an environmental hazard on Kafoury Neighborhood, this was confirmed after querying a sample of Kafoury residents about the health damage that can be caused by polluted atmosphere and results confirmed that the KNTPS has an adverse impact on the target area, that means KNTPS must use high quality Flue Gas Desulfurization system in all of the three operating units and use a high quality fuel which contains lower amount of sulfur. Finally, Sudanese government and Ministry of Environmental and Health should monitor the environmental situation of KNTPS and impose sanctions in case of infringe of environmental regulations.
