Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. Weir height for a bubble cap plate column is the same as that for a seive plate 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 in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate Weir height for a bubble cap plate column is the same as that for a seive plate 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 in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate ANSWER DOWNLOAD EXAMIANS APP
