To avoid the tearing off the plate of an edge, the margin (i.e., the minimum distance from the centre of the rivet hole to the nearest edge of the plate) should be equal to
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
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
Flash distillation, differential distillation & steam distillation are all continuous distillation processes
