Pick out the wrong statement about distillation operation

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

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 pertaining to the design of the distillation column.

The purpose of the slot is to disperse the gas into the liquid in the form of small bubbles

None of these

If sufficient slot area is not provided, the gas may pass through the skirt clearance

Generally, a skirt clerance of 0.5" to 1.5' is recommended to prevent plugging of the slots by residue build up
