In case of an absorber, the operating _______________?
Correct answer: A. Line always lies above the equilibrium curve
- A. Line always lies above the equilibrium curve
- B. Line always lies below the equilibrium curve
- C. Line can be either above or below the equilibrium curve
- D. Velocity is more than the loading velocity
Explanation
For absorption, the operating line normally lies above the equilibrium curve on a y-x diagram, providing a positive concentration driving force for transfer from gas to liquid. If it crossed below the equilibrium curve, the assumed absorption direction would not be maintained.
