Pick out the wrong statement about distillation operation

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

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

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

Distillation under vacuum is a substitute for steam distillation

Pick out the wrong statement about the design of seive plate column and the bubble cap column.

Weir length for a bubble cap plate is the same as that for the seive plate

Weir height for a bubble cap plate column is the same as that for a seive plate column

Weir height in case of a bubble cap plate ranges from 50 to 150 mm and is higher than the seive plate

The downcomer design and the residence time in the downcomer is almost same for seive plate and bubble cap columns
