An absorption tower is used to purify stack gas of a plant. It is desired to absorb 95% of the SO2 from stack gas containing 5% SOz in a countercurrent stage tower. Total inlet gas flow to tower is 100 kg mol/h, and total inlet pure water used as absorbent is 270 kg mol/h. The equilibrium relation for SOz-water is yA = 2 XA. Determine the number of theoretical stages required for this separation.
