Which term is an alternative name for the fractionating column used in refining, also known as pipestill?

• A. Fractionation or fractionating column (also pipestill)
• B. Distillation column
• C. Reformer
• D. Cracker

Answer: (A)

In refining, the equipment that separates crude oil into fractions is the fractionating column, a specialized distillation column. The exact alternate name for this unit is “fractionation” or “fractionating column,” with “pipestill” as an older nickname. This makes the term a precise label for the same piece of equipment and its historic name. A distillation column is a broader category of equipment and doesn’t specify the alternate naming used for the fractionating column. Reformers and crackers are different processing units entirely, not synonyms for the fractionating column.
