The corrosive and fouling fluid should be preferably routed through the tubes
Lower flow rate fluid should be routed through the shell side
The viscous fluid should be routed through the shell side
Higher pressure fluid stream should be routed through the shell side

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
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
