Introduction to column distillation distillation is the most common separation technique in chemical process industry, accounting for 9095% of the separation operations this is why more than a half of this course is devoted to distillation or column distillation, which includes binarymixture distillation. The first column acts as an extractive column where the solvent is introduced at the second stage of the column, so that it will be present throughout the column and exits with the bottoms. Extractive distillation is a vaporliquid process operation that uses a third component, or solvent, to effect a chemical separation the extractive agent creates or enhances the volatility difference between the components to be separated. The process utilizes the difference of the vapor pressures to produce the separation.
