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_________________?

Correct answer: E. All A, B. & C.

A. is more accurate in finding the number of equilibrium stages
B. accounts for the enthalpy changes in the process
C. Facilitates direct calculation of heat load on reboiler & condenser from, the diagram used in
D. this method
E. All A, B. & C.

Explanation

Ponchon-Savarit uses enthalpy-composition data, so it includes heat effects, gives a more rigorous stage calculation, and permits direct determination of condenser and reboiler duties. Thus all three listed advantages apply.
