Abstract
Misr Fertilizers Production Company (MOPCO) at Damietta, North Egypt was used as a case study to monitor indoor and outdoor air emissions to find out the main sources of air pollution and evaluate the air quality in the facility.
Monitoring of carbon monoxide (CO), nitrogen dioxide (NO2), ammonia (NH3) and sulfur dioxide (SO2) in addition to dust, noise and heat stress was carried out in the production units in MOPCO (e.g., filling area, ammonia pumping area, and boiler area (BFW) from January 2018 to July 2019.
Furthermore, outdoor air emissions were measured from the outlet stacks of granulation, reformer, and the boiler in MOPCO. The obtained results from the three sites were less than the maximum permissible limits for CO (25 ppm), SO2 (2 ppm), NO2 (3 ppm), and NH3 (25 ppm) according to the Egyptian Environment Protection Low No. 4/1994 and its amendments (No. 9/2009) (EEL4, 1994).
The hazard modelling for indoor air emissions in the production units at MOPCO was calculated using Risk Calculator software. The model results showed that MOPCO has low values of dust, heat stress and noise, as well as low emissions of CO, NH3 and SO2 in workplace.
Dust (PM10) increases in the Urea Storage unit in MOPCO because of increasing the production especially in October and November, while it decreases in the Urea Bagging Cars because it is an open unit. Dust values in MOPCO are within he dust safe limit (3 mg/m3/8 hours) according to Egyption Environment Law (EEL4, 1994) and compared to those of the Emethanex Plant which has PM10 in arrange of 32-44 µg/m3.
The Noise measurements in MOPCO are within safe limits (90 dB), with work regulations to protect the workers.
Heat stress increases in the Urea Storage and beside the Boiler in summer and decreases in all office units and in the Urea Bagging unit because it is an open area.
Detailed air dispersion modeling (AERMOD) was applied to determine the likelihood ground level concentrations resulting from the outdoor air emissions of NO2, NH3, CO and PM10 from the stacks in MOPCO.
