Question

Problem 2: A contaminated soil contains 100 mg metals/kg soil (all metals are readily condensable), 50,000 mg S/kg soil, 1,000 mg F/kg soil, 980 mg/Kg of VOCs and 40,000 mg Cl/kg soil and is decontaminated by using incineration The incinerator is operated at a heat loading of 63 MM Kilojoules/hour and has an estimated stack gas flow of 986 m3/minute. The rate at which soil is fed into the incinerator is 3,400 g/hour. Using the EPA uncontrolled source emission factors given below, estimate the hourly emissions that would be expected for each pollutant in the flue gas of this incinerator if no air pollution control equipment were used (Draw a process flow diagram and show all of your calculations) Pollutant VOCs Metals HCI HF SO PM CO NO Emission Factors 0.1 g/kg VOC in waste feed 50.0 g/kg metal in waste feed 1.03 g/g Cl in waste feed 1.05 g/g F in waste feed 2.00 g/g S in waste feed 11,750 mg/m3 flue gas 0.05 kg/MMKJ 0.15 kg/MMKJ
