A gas stream contains 4.0 mol % NH3 and its ammonia content is reduced to 0.5 mol % in a packed absorption tower at 293 K and 10
1300 Pa. The inlet pure water flow is 68.0 kgmol/h and total inlet gas flow is 57.8 kgmol/h. The tower diameter is 0.747 m. The film mass-transfer coefficients are k’ya=0.0739 kgmol/s.m3 .molfrac and k’xa= 0.169 kgmol/s.m3 .molfrac. Using the design methods for dilute gas mixtures,
(a) Calculate the tower height using k’ya.
(b) Calculate the tower height using K’ya.

Answer:
Explanation:
Given V1 = 100m3
P1 = 50bar
P2 = 300bar
T1 = 150°C = 150°C + 273 = 423k
Applying the ideal gas equation ; Pv = mRT
Plugging in the values given to get the mass of the carbon dioxide, the detailed steps and appropriate calculation is as shown in the attached file.
