2500 L/min of a gas mixture containing 27% of a pollutant (Y = 0.5X where X and Y are mole RATIOS) by mole shall be treated in a packed absorber using No. 1 plastic Super Intalox saddles. 98% of the ammonia is to be absorbed using pure water with rate which is 1.25 times the minimum. Operating conditions are 1.5 atm and 30oC. Mass transfer coefficient KG is 0.5 kmol/(hr-m2-atm).

Determine the tower diameter and height.
