In a counter-current extractor, as the axial mixing increases, the extraction efficiency______________________?
Correct answer: B. Decreases
- A. Increases
- B. Decreases
- C. Remains unchanged
- D. Depends on the pressure of the system
Explanation
Axial mixing causes back-mixing, reducing the concentration-driving force toward the ideal counter-current profile. Consequently, extraction efficiency decreases as axial mixing increases.

At equilibrium the concentration of water in vapour phase (C*) in kg/m3 of air space and the amount of water (m) adsorbed per kg of dry silica gel are related by, C* = 0.0667m. To maintain dry conditions in a room of air space 100m3 containing 2.2 kg of water vapour initially, 10 kg of dry silica gel is kept in the room.
