Pick out the wrong statement about distillation operation

In flash (equilibrium) distillation, a definite fraction of liquid is vaporised in such a way that the evolved vapour & residual liquids are in equilibrium with each other

Flash distillation, differential distillation & steam distillation are all continuous distillation processes

In differential (simple) distillation, the vapour is removed as soon as it is formed without appreciable condensation

Distillation under vacuum is a substitute for steam distillation

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

Accounts for the enthalpy changes in the process

Is more accurate in finding the number of equilibrium stages
