Maximum size of the raschig rings used in a packed tower is about _______________ of the column diameter?
Correct answer: C. 1/30th
- A. 1/10th
- B. 1/20th
- C. 1/30th
- D. 1/50th
Explanation
Raschig rings should not be excessively large relative to the tower because poor liquid distribution and wall effects result. A commonly used upper limit is approximately one-thirtieth of the column diameter.
