You are now tasked with designing an absorption tower to remove ammonia from an air stream using pure water. The absorption tower will be operated at the same temperature and pressure as your laboratory experiments above. The gas stream entering the absorption tower contains 5 mol% ammonia. Your overall separation objective is to remove ammonia from this gas stream so that the gas flow exiting the absorption tower has 0.1 mol% ammonia. The inlet gas molar flow rate is 10 kg-mole/hour. The inlet water molar flow rate is 25 kg-mole/hour. Use the graphical approach to determine the number of (theoretical) stages needed to carry out the proposed separation. Label the mole fractions of ammonia in both the liquid and gas phases at each stage. You are now tasked with designing an absorption tower to remove ammonia from an air stream using pure water.
