Which of the following packing materials provides for maximum mass transfer ?
Correct answer: B. Cross-partition rings
- A. Raschig rings
- B. Cross-partition rings
- C. Raschig rings
- D. All give the same value
Explanation
Cross-partition rings provide greater wetted surface area and improved gas-liquid contact than ordinary Raschig rings, giving higher mass-transfer performance. Options a and b are duplicate listings of Raschig rings.
