What is meant by enhanced distillation?

Expert Solution
Step 1

The definition of enhanced distillation is to be mentioned.

Step 2

The normal distillation process sometimes not much beneficial in achieving the desired amount of purity of the two components and thus the distillation will be made complex by certain other processes. This whole procedure is known as the enhanced distillation.

The enhanced distillation found applications in following scenario:-

1. When there is a formation of certain type of azeotrope in the mixture.

2. When the driving force of distillation which is known as the relative volatility is less than 1.

3. When there is a difference of less than 500C between the components present for distillation.
