Process Equipment and Plant Design
In a shell and tube heat exchanger for a given heat transfer surface area, smaller diameter tubes are favoured as compared to larger diameter ones ; because the smaller diameter tubes

Can be fitted into a smaller shell diameter hence the cost of the heat exchanger would be less

Are easier to clean

Are less prone to fouling

None of these

Pick out the wrong statement about distillation operation

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

Distillation under vacuum is a substitute for steam distillation

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

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