For absorbing a sparingly soluble gas in a liquid, the_____________________?
Correct answer: B. Liquid side coefficient should be increased
- A. Gas side co-efficient should be increased
- B. Liquid side coefficient should be increased
- C. Gas side co-efficient should be decreased
- D. Liquid side co-efficient should be decreased
Explanation
A sparingly soluble gas offers high resistance in the liquid film, so the liquid-side mass-transfer coefficient should be increased. Improving the gas-side coefficient has relatively little effect when liquid-film resistance dominates.
