Meaning and Definition
A vertical industrial apparatus used in chemical engineering and refining processes to separate a mixture of liquids into its individual components (fractions) based on their different boiling points.
A tall column fitted with internal trays, plates, or packing material that facilitates continuous distillation by providing a large surface area for vapor and liquid to interact, allowing more volatile components to ascend as vapour and less volatile ones to descend as liquid.

FAQ
Frequently Asked Questions
Yes, the terms are often used interchangeably. 'Fractionating column' emphasises the separation into fractions, while 'distillation column' names the overall process.
Primarily in oil refineries, petrochemical plants, chemical manufacturing facilities, and some large-scale laboratory or pilot plant settings.
It contains internal structures like trays, plates, or a packed bed of material (e.g., rings, saddles) to maximise contact between rising vapour and descending liquid.
The principle is similar in cryogenic air separation (distilling liquid air), but the term is most strongly associated with the separation of liquid mixtures at various temperatures.
A vertical industrial apparatus used in chemical engineering and refining processes to separate a mixture of liquids into its individual components (fractions) based on their different boiling points.
