Process Equipment and Plant Design
In seive plate column, holes are drilled or punched in sizes ranging from 2.5 to 12 mm (5 mm being widely used). The hole pitch is normally __________ times the hole diameter to give the required hole area.
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
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
