Extractive Distillation

Extractive distillation also involves the addition of the third component to the mixture (solvent or entrainer). However, in the case of extractive distillation, the solvent is a relatively high boiling point material, which is present at high concentration on each stage and exits at the bottom. To improve the efficiency of the process, the entrainer has to be added

at the top of the column, so that its concentration on each stage will be enough to produce the desired effect in the equilibrium of the original mixture. Finally, the entrainer is separated from the bottoms product in another distillation column.

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming.
