In case of a desorber (stripper), the________________?
Correct answer: B. Operating line always lies below the equilibrium curve
- A. Operating line always lies above the equilibrium curve
- B. Operating line always lies below the equilibrium curve
- C. Temperature remains unaffected
- D. Temperature always increases
Explanation
In a stripper, the liquid transfers solute to the gas, and the operating line lies below the equilibrium curve on the usual y-x diagram. This position provides the positive driving force needed for desorption.
