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 Feed is not at its bubble point Number of equilibrium stages required is likely to be very small Number of equilibrium stages in only stripping section is to be calculated Relative volatility is close to one (e.g., separation of close boiling isomers) Feed is not at its bubble point Number of equilibrium stages required is likely to be very small Number of equilibrium stages in only stripping section is to be calculated Relative volatility is close to one (e.g., separation of close boiling isomers) ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In actual operation of distillation column, the vapour is not distributed uniformly among the bubble caps, primarily because of the Lower skirt clearance Liquid gradient on the tray Lower static submergence Small downcomer liquid seal Lower skirt clearance Liquid gradient on the tray Lower static submergence Small downcomer liquid seal ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Weep holes provided in the plates of a distillation column Facilitate draining out liquid from a tray when the unit is not in operation Must be large enough (usually 1/4" to 5/8" dia) to prevent plugging but should not deliver excessive amount of fluid during operation Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid All of these Facilitate draining out liquid from a tray when the unit is not in operation Must be large enough (usually 1/4" to 5/8" dia) to prevent plugging but should not deliver excessive amount of fluid during operation Are normally located near the overflow weir so that any delivery of liquid during operation follows approximately the same path as the overflow fluid All of these ANSWER DOWNLOAD EXAMIANS APP
