A factory uses 3 x 105 gallons of fuel oil (specific density 0.97) per month. The emission rate of air pollutants per one million litres of oil used per year is: Particulate matter = 3.0 tonnes, SO emission: 50 tonnes, NO, emission is 7.0 tonnes, hydrocarbon emission = 0.5 tonnes, and CO emission= 0.5 tonnes. If a tall stack of 200 m is used for air pollution control and has the efficiency to remove 50% of the air pollutants, calculate the exit concentration of the air pollutants in ug/m on an hourly basis, assuming a gas flow rate of 200 m/min, and exits the stack at STP. Make any relevant assumptions required.
