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 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 ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design Smoker's equation for the calculation of number of equilibrium stages in a continuous binary distillation column is used, when the Number of equilibrium stages required is likely to be very small Relative volatility is close to one (e.g., separation of close boiling isomers) Number of equilibrium stages in only stripping section is to be calculated Feed is not at its bubble point Number of equilibrium stages required is likely to be very small Relative volatility is close to one (e.g., separation of close boiling isomers) Number of equilibrium stages in only stripping section is to be calculated Feed is not at its bubble point ANSWER DOWNLOAD EXAMIANS APP
