Pick out the wrong statement about the design of seive plate column and the bubble cap column.

The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns

Weir length for a bubble cap plate is the same as that for the seive plate

Weir height for a bubble cap plate column is the same as that for a seive plate column

Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate

Process Equipment and Plant Design
A certain pressure vessel manufacturer avoids doing reinforcements calculations for openings by always providing a reinforcing pad extending upto double the diameter of the opening and of the same material and thickness as that of the shell wall. If area compensation is accepted as a code guideline, his approach leads to safe design

Irrespective of the shape of the vessel

Only if the opening is on a vertical cylinderical vessel

Only if the opening is on a horizontal cylinderical vessel

Only if the opening is on spherical vessel

Irrespective of the shape of the vessel

Only if the opening is on a vertical cylinderical vessel

Only if the opening is on a horizontal cylinderical vessel

Only if the opening is on spherical vessel
