Question

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).

Explanation / Answer

If pollution control equipment is installed to remove 95.5% of the PM and 99.96% of the VOC emissions, what would be the new hourly emissions in the flue gas? Support your results with all assumptions that you must make.
