Question
In a packed bed tower air is purified from methanol by using water. Tower has a cross
sectional area of 0.2 m? and system operates at 313.1 K and 101.32 kPa. The inlet air
contains 10 mol% methanol and at outlet the concentration of methanol drops to 2 mol%.
The gas flow is 20 kg mol inert air/h. The pure inlet flow is 50 kg mol water/h. Film
coefficients for the given flows in the tower are k',a= 0.07 kg mol/s.m³.mol frac and k',a=
0.04 kg mol/s.m³.mol frac. Equilibrium data is given below. Calculate the tower height.
