In a packed absorption tower, if the equilibrium and operating lines are both straight lines, then the ratio, HETP/HTUOG ______________ the absorption factor?
Correct answer: C. Both A. and B.
- A. Increases with increase in
- B. Is one at unity value of
- C. Both A. and B.
- D. Neither A. nor B.
Explanation
For straight equilibrium and operating lines, HETP/HTUOG is proportional to A ln A/(A−1), where A is the absorption factor. This ratio equals one when A equals one and increases as A increases, so both A and B apply.
