Process Equipment and Plant Design
A high vapour velocity is required for high plate efficiency in a seive plate coloumn. The satisfactory value of operating vapor velocity for design purpose in seive plate column is about __________ percent of the flooding velocity.
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
