Question
A 300 cfm stream of an airSO2 mixture containing 16.2% SO2 by volume at 68 F and 1.0 atm is to be scrubbed with water
A 300 cfm stream of an air‐SO2 mixture containing 16.2% SO2 by volume at 68 °F and 1.0 atm is to be scrubbed with water in a countercurrent packed tower for the purpose of recovering 95% of the SO2. The tower operates at constant temperature.
- Draw the equilibrium line
- Determine the inlet and outlet mole fractions in water and air
- Draw the minimum operating line
- Calculate the minimum water requirement.
Equilibrium data Liquid mole fraction of SO2 0.0014 0.0028 0.0056 0.00840 0.0139 Mole fraction of SO2, in gas phase 0.034 0.078 0.162 0.217 0.442
