An existing rural power plant has been found to produce an SO2 concentration of 30 mg/m3 at a distance of 800 m directly downwind from stack when the wind is 4 m/sec from the north during a class C stability situation and the atmospheric temperature is 20℃. At a later date, another plant is built 200 m to the west of the original plant. It burns 4000 lb/hr of fuel oil contains 0.5 percent sulfur. The second plant has a...

A new industrial facility is proposed at a location 5 km upwind from an existing multi- family residential development. The exhaust of the factory emits chloropicrin at the rate of 2500 g/s. The detection threshold for chloropicrin is 10 μg/m2. The atmospheric stability conditions for the area changes between stability classes D&F and the average wind speed is 5.0 m/s. Would should be the minimum recommended height for the smoke stack of that industrial facility? (Hint: we are concerned with...

A gas is separated from the air using an absorption column, which is randomly packed with 25mm metal Pall rings. Pure liquid solvent is used to reduce the mole fraction of gas A in air from 0.05 to 0.005 at a constant pressure and temperature. Total molar flow rates of entering gas and liquid to the column are 120 kmol/h and 180 kmol/h, respectively. The equilibrium relationship at operating conditions is y∗ = 1.2 x and the gas side pressure...
