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.
