Use of raschig rings in place of crushed stones as packing in packed beds (other things being same) ?
Correct answer: C. Decreases pressure drop, increases surface area
- A. Increases pressure drop, increases surface area
- B. Increases pressure drop, decreases surface area
- C. Decreases pressure drop, increases surface area
- D. Decreases pressure drop, decreases surface area
Explanation
Raschig rings offer more effective contact area and generally a more open passage than irregular crushed stone. For the same bed conditions this gives increased surface area with reduced pressure drop.
