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 Small downcomer liquid seal Liquid gradient on the tray Lower skirt clearance Lower static submergence Small downcomer liquid seal Liquid gradient on the tray Lower skirt clearance Lower static submergence ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Ponchon Savarit method is based on the use of enthalpy concentration diagram, which contains the bubble point curve (saturated liquid curve), dew point curve (saturated vapour curve) and equilibrium tie lines. As compared to McCabe-Thiele's method, this method Accounts for the enthalpy changes in the process Is more accurate in finding the number of equilibrium stages Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method All of these Accounts for the enthalpy changes in the process Is more accurate in finding the number of equilibrium stages Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method All of these ANSWER DOWNLOAD EXAMIANS APP
