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 Is more accurate in finding the number of equilibrium stages Accounts for the enthalpy changes in the process All of these 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 Accounts for the enthalpy changes in the process All of these Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in this method ANSWER DOWNLOAD EXAMIANS APP

Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Can accomodate less number of tubes for a given shell diameter Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design For a cylinderical vessel of moderate height, the weld joint efficiency for joints parallel to the cylinderical axis is given as 1.0, while for joints along the girth (circumference) it is given as 0.8.
