What is Stripping section and Rectifying section in Distillation Column?

In a distillation column, which is a key unit in chemical and petrochemical processes for separating liquid mixtures into their individual components, there are two main sections: the Stripping Section (also known as the Reboiler Section) and the Rectifying Section (also known as the Condenser Section). Location: The Stripping Section is located at the bottom of the distillation column. Function: The primary function of the Stripping Section is to vaporize the components with higher boiling points from the liquid mixture. This is achieved by providing heat, often through a reboiler, which causes the liquid to boil and generate vapor. The vapor rises through the column, carrying with it the less volatile components. Location: The Rectifying Section is situated at the top of the distillation column. Function: The primary function of the Rectifying Section is to condense the vapor rising from the Stripping Section back into liquid.
