Pick out the wrong statement about distillation operation________?
AIn differential (simple) distillation, the vapour is removed as soon as it is formed without appreciable condensation
BFlash distillation, differential distillation & steam distillation are all continuous distillation processes
CIn 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
DDistillation under vacuum is a substitute for steam distillation
Correct answer
B. Flash distillation, differential distillation & steam distillation are all continuous distillation processes
Explanation
The correct answer is Flash distillation, differential distillation & steam distillation are all continuous distillation processes.
