Measurement of Air pollution Emissions from Chimneys of Production Units Moisture Insulation (Isogam) Delijan

Isogam (Waterproofing) Bituminous production units as one of the major sources of air pollutants, make concerns for environmental organizations, research centers and industries in order to mitigate their destructive impacts on the atmosphere. Due to importance of application of these materials in building sectors, many producing units have been developed in Iran. It confronts many Iranian cities with an environmental crisis. Therefore, accurate analysis of pollutant emissions is an essential step while presenting strategies to minimize its harmful effect. Isogam Bituminous production process includes non-hydrocarbon emissions and hydrocarbon gases.The purpose of this research is to measure exhaust gas emissions of the production units of Isogam Bituminous Delijan such as CO, HC, CO2 , SO2 and NOX (NO+NO2), contrasting with the conventional standards.

In this research, various values of volumetric gas concentrations (ppm) are measured by analyzer machine named Testo350. Then to analyze the quality of the exhaust gas the health, safety and environmental standards would be applied to the specimen.

According to the presented results, CO is the highest part of pollutants which is 678 ppm in winter and the highest average concentration of hydrocarbons in the summer is 250.

This study shows that as the values ​​of some parameters is greater than the standard values of exhaust chimney, it is necessary to review the control systems to optimize the emission of pollutants.
