distillation column
Quick Summary
A distillation column is a chemical instrument used in the process of distillation, which separates components of a liquid mixture based on their different boiling points. The process involves heating the liquid to create vapor, which is then cooled and condensed back into a liquid form.12
In a distillation column, this separation is achieved more efficiently than in simple distillation. Vapors rise through the column, condensing and revaporizing as they encounter cooler surfaces and rising hot vapors. This countercurrent interaction allows for a more refined separation, concentrating the lower-boiling point substances at the top of the column and the higher-boiling point substances at the bottom.12
Distillation columns are crucial in various industries, including petroleum refining for separating crude oil into fractions like gasoline and kerosene, and in chemical processing and desalination.13

The condensed liquid flows back toward the solution until it meets rising hot vapors, whereupon the more volatile portion of the returning liquid revaporizes, and the less volatile part of the rising vapor condenses. Thus in the column there occurs a multistage operation, the outcome of which is…
