Entrainer used in Azeotropic distillation should____________________?
Correct answer: A. Form a low boiling azeotrope with one of the constituents of the mixture
- A. Form a low boiling azeotrope with one of the constituents of the mixture
- B. Form a new azeotrope of low relative volatility with one of the constituents of the mixture
- C. Have high latent heat of vaporisation
- D. Have high viscosity to provide high tray efficiency
Explanation
An effective entrainer forms a low-boiling azeotrope with one component, allowing that component to be removed overhead and breaking the original separation difficulty. A low relative volatility would make separation harder, not easier.
