Abstract

Air pollution is defined as the presence of unwanted substance in the air medium which alters its quality. The substance which is present in the air medium which alter its quality is called as the pollutant. The main source of man-made air pollution are Industrial Emission and the Vehicular emission. Both the Industries as well as the Vehicles majorly uses liquid form of fuels for their operations. Both the Industries as well as the vehicles were at very high rate in case of the urban cities. Manali, the Northern part of Chennai city was selected for the study and industries were located within it. Industries were identified based on the usage of liquid form of fuel. The industries considered for the studies are Food and Beverage industry and the Rubber tyre manufacturing industry. The fuels used in the respective industries are high speed diesel and the furnace oil. Emission results were achieved through the stack monitoring. Stack monitoring was performed as per IS: 11255 (Part 1, Part 2 and Part 7)- 1985 procedure. The stack parameters considered for the studies are stack diameter, stack height, stack temperature, stack discharge and the stack velocity. Stack emission parameters considered for the studies are SOx and NOx Stack monitoring was conducted under two scenarios namely fully loading and partially loading of fuel rate. The stack monitoring results shows that the temperature produced from the stacks with respect to the partly loaded fuels shows the higher rate of stack temperature when compared to the fully loaded fuel. This excess temperature increases the concentration of the stack emissions. Thus it is concluded that the gaseous emissions coming from the stacks operated with the partial fuel rate will be higher when compared to the stacks operated with the fully loaded fuel rate.
