Design Of Distillation Column

Azeotropic distillation of ethanol-water mixture is accomplished by adding a volatile third component to the liquid which changes the volatility of one of the two components more than the other so the components are separated by distillation. The two components to be separated often have similar boiling point components which do or do not azeotrope in the binary mixture, but sometimes there are components which do azeotrope despite having vastly different boiling points. It is likely that in some cases, one system can be separated either by azeotropic distillation or by extractive distillation…
