A process is carried out for the feed mixture of 95% air and 5% ammonia vapor, the compressor recovered 40% of ammonia, what is the exit pressure of the compressor, if the partial pressure of ammonia vapor is 10 mm Hg?
  • a)
    225.4 mm Hg
  • b)
    326.8 mm Hg
  • c)
    451.2 mm Hg
  • d)
    593.5 mm Hg
Correct answer is option 'B'. Can you explain this answer?

Exit components, ammonia: 0.05*0.6 = 0.03, air: 0.95, ⇒ yammonia = 0.03/0.98 = 0.0306, ⇒ Total exit pressure = 10/0.0306 = 326.8 mm Hg.

Calculation of Exit Pressure of the Compressor:
- Given:
Feed mixture composition: 95% air and 5% ammonia vapor
Recovery of ammonia by compressor: 40%
Partial pressure of ammonia vapor: 10 mm Hg

Calculating the partial pressure of ammonia in the feed mixture:
Partial pressure of ammonia = 5% of total pressure
Assuming total pressure of feed mixture = 1 atm = 760 mm Hg
Partial pressure of ammonia = 5% of 760 mm Hg = 0.05 * 760 = 38 mm Hg

Calculating the partial pressure of recovered ammonia:
Partial pressure of recovered ammonia = 40% of the partial pressure of ammonia in feed mixture
Partial pressure of recovered ammonia = 0.40 * 38 mm Hg = 15.2 mm Hg

Calculating the partial pressure of remaining ammonia in the exit stream:
Partial pressure of remaining ammonia = Partial pressure of ammonia in feed mixture - Partial pressure of recovered ammonia
Partial pressure of remaining ammonia = 38 mm Hg - 15.2 mm Hg = 22.8 mm Hg

Calculating the total exit pressure of the compressor:
Total exit pressure = Partial pressure of remaining ammonia + Partial pressure of air
Total exit pressure = 22.8 mm Hg + 760 mm Hg = 782.8 mm Hg
Therefore, the exit pressure of the compressor is 782.8 mm Hg, which is closest to option b) 326.8 mm Hg.
