Process Equipment and Plant Design
A certain pressure vessel manufacturer avoids doing reinforcements calculations for openings by always providing a reinforcing pad extending upto double the diameter of the opening and of the same material and thickness as that of the shell wall. If area compensation is accepted as a code guideline, his approach leads to safe design
Only if the opening is on a vertical cylinderical vessel
Only if the opening is on spherical vessel
Irrespective of the shape of the vessel
Only if the opening is on a horizontal cylinderical vessel
Distillation under vacuum is a substitute for steam distillation
In differential (simple) distillation, the vapour is removed as soon as it is formed without appreciable condensation
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
