Process Equipment and Plant Design Pick out the wrong statement about the design of seive plate column and the bubble cap column. 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 Weir length for a bubble cap plate is the same as that for the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns 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 Weir length for a bubble cap plate is the same as that for the seive plate The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns ANSWER DOWNLOAD EXAMIANS APP
