Vacuum distillation is conventional distillation carried out under vaccum. This process can be used for system having low relative volatility. Azeotrope is a liquid mixture that produces a vapour that has the same composition as that of the liquid and hence can not be separated by simple distillation. In azeotropic distillation a third substance is added to shift the azeotropic point to a more favourable position. The added component, called agent, interacts with one of the component and enables the separation of the liquid mixture. The agent thus increases the relative volatility of the liquid mixture. The agent comes out of the column with one of the component is separated subsequently. In certain azeotropic mixtures vacuum distillation may be tried to shift the azeotropic point. However this needs to be tested. Hope this answers your question.
If Cost of extraction+ distillation for a +(b+c ) separation for (B and c separation again distillation) is less than for simple a to b distillation we use this hybrid method, it's all about money ~ Lisa Listen my money talk
Thanks for video.pls keep posting
Thanks Very informative sir 👍. Just one point @14:09 it will be reactangular valve tray. Probably that's typo error.
Thank you sir
very Helpful thanks sir ...
You are welcome
Sir, please tell the Difference between vaccum distillation and azeotropic distillation
