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:
The volume of the gas is 11.2 L.
Explanation:
Initially, we have:
V₁ = 700.0 L
P₁ = 760.0 mmHg = 1 atm
T₁ = 100.0 °C
When the gas is in the thank we have:
V₂ =?
P₂ = 20.0 atm
T₂ = 32.0 °C
Now, we can find the volume of the gas in the thank by using the Ideal Gas Law:
(1)
Where R is the gas constant
With the initials conditions we can find the number of moles:
(2)
By entering equation (2) into (1) we have:
Therefore, When the gas is placed into a tank the volume of the gas is 11.2 L.
I hope it helps you!
