trays estimation ( 30 points) MW=17kg/kgmol) in a tray tower is used to remove 99% of ammonia (NH, , the reactor outlet. The air air (MW=28.97kg/kgmol) stream which is coming from Kpa, which enter the tower air stream contains 6mol% ammonia at 30C and 101.325 (MW=18kg/kgmol) entering at flowrate of 128kg/hm2. The flow rate of pure water The equilibrium of the entering the tray is 188kg/hm2. Where y= mole fraction of NH3 in gas phase, and x= mole fraction of NH3 in liquid phase By assuming that the ammonia concentration is sufficiently dilute throughout the tower that both operating and equilibrium curves are linear. a) Draw a sketch of the tray tower showing the amounts of inlet and outlet streams including the mole fraction and mole ratio of each component in each stream. b) Determine the number of theoretical trays (N) graphically. c) Determine the number of theoretical trays (N) analytically) using the Kremser-Brown-Souders (KBS) equation.
