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 Is more accurate in finding the number of equilibrium stages All of these Accounts for the enthalpy changes in the process Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method Is more accurate in finding the number of equilibrium stages All of these Accounts for the enthalpy changes in the process ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement pertaining to the design of a horizontal tube evaporator. It is unsuitable for concentrating those liquids, which form a scale or deposit salt Liquor flows inside the tube, while the steam is outside submerging the tube It is suitable for process, in which the final product is a liquor instead of solid Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres It is unsuitable for concentrating those liquids, which form a scale or deposit salt Liquor flows inside the tube, while the steam is outside submerging the tube It is suitable for process, in which the final product is a liquor instead of solid Its usual dimensions are: tube dia = 2-3 cms; evaporator body dia = 1-4 metres and evaporator height = 2.5-4 metres ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Pick out the wrong statement about routing of fluids in a shell and tube heat exchanger. The corrosive and fouling fluid should be preferably routed through the tubes Lower flow rate fluid should be routed through the shell side Higher pressure fluid stream should be routed through the shell side The viscous fluid should be routed through the shell side The corrosive and fouling fluid should be preferably routed through the tubes Lower flow rate fluid should be routed through the shell side Higher pressure fluid stream should be routed through the shell side The viscous fluid should be routed through the shell side ANSWER DOWNLOAD EXAMIANS APP
