Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of the distillation column. If sufficient slot area is not provided, the gas may pass through the skirt clearance The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles None of these Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up If sufficient slot area is not provided, the gas may pass through the skirt clearance The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles None of these Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up 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 Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method All of these Is more accurate in finding the number of equilibrium stages Accounts for the enthalpy changes in the process Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method All of these Is more accurate in finding the number of equilibrium stages Accounts for the enthalpy changes in the process ANSWER DOWNLOAD EXAMIANS APP
