We are going to design a desorber to remove CO₂, the CO₂ comes from an effluent solution of 4 m³/h and we want to reduce the concentration of CO₂ to 1.5 kg/m³ at 0.02 mol/m³ by stripping with air in a packed stripping column operating at 20 and 1 bar.

The CO₂ contained in the air is 0.03% volume and we want it to come out with a concentration that does not exceed 1% volume, random packages of 35 mm plastic pal rings are used.

Column diameter=0.32 m Slope of the Equilibrium Curve=1440

Perform the material balances and obtain the fractions at the entrance and exit of the column.
