Overall mass transfer co-efficient in case of absorption of __________ in water is based on the gas film co-efficient only, as the mass transfer process is gas film (phase) controlling ?
Correct answer: C. NH3
- A. CO2
- B. SO2
- C. NH3
- D. None of these
Explanation
Ammonia is highly soluble in water, so the liquid-side resistance is small and the gas-film resistance controls the overall absorption rate. Hence the overall coefficient is approximately based on the gas-film coefficient.
