Pick out the wrong statement about the design of sieve plate column and the bubble cap column ?
Correct answer: D. Weir height for a bubble cap plate column is the same as that for a sieve plate column
- A. The downcomer design and the residence time in the downcomer is almost same for sieve
- B. plate and bubble cap columns
- C. Weir length for a bubble cap plate is the same as that for the sieve plate
- D. Weir height for a bubble cap plate column is the same as that for a sieve plate column
- E. Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the
- F. sieve plate
Explanation
The downcomer arrangement and weir length are broadly comparable for sieve and bubble-cap trays, but bubble-cap trays normally use a higher outlet weir. Hence the statement that their weir heights are the same is the wrong one.
