- W2215665246 abstract "Three air pollutant gases, sulpher dioxide, nitrogen oxide and ammonia emitted from two thermal energy stations at Khartoum North and Garri Oil Refinery at ground level were detected. Parameters measured included ground level concentration, relative humidity, temperature (maximum and minimum) and wind (velocity and direction). Analysis of gases emitted concentration was done according to Adam’s 3 Advanced Model and server software package. Passive Diffusion Tubes were analyzed by GC- Ms, IC, and UV spectroscopy. Results showed that sulpher dioxide concentration at ground level ranged 0.78- 9.61 µg/ m3 and 0.29- 3.6 ppb for Khartoum North Power Station (KNPS) while the values for Garri Power Complex (GPC) were also below the limit of detection ranged <0.53- 1.67 µg/ m3and 0.20- 0.62 ppb. The values for the concentrations of SO 2 were lower when compared to UK, EU and WHO, 20 µg/ m3and 50 µg/ m3 respectively while The USA: National Ambient Air Quality Standard (NAAQS) is 80 µg/ m3. Nitrogen dioxide detected at ground level was 9.69- 29.98 µg/ m3 and 5.05- 15.61 ppb for (KNPS) while 6.92- 33.66 µg/ m3 and 3.60- 17.53 µg/ m3 for (GPC). The values of NO2 emitted from both power stations were lower than UK, EU 40 µg/ m3 and USA 100 µg/ m3. Ammonia gas was detected at (GPC) which is the main thermal energy supply of (KOR). The highest concentration of Ammonia emitted by (GPC) at 2 Km S distance was 12.736 ppb, 9.03 µg /m3 and 12.292 ppb, 8.718 µg /m3 at 2 Km N. Similarly high values of concentrations of sulpher dioxide reported for (GPC) at the same distances and wind direction, 2Km S 1.67 µg /m3 and 2 Km N 1.44 ppb. All of ammonia values reported was below 0.6-0.7 ppm odor threshold. The values of ammonia are lower than USA 20µg/m 3 ." @default.
