Crude Oil Distillation Concepts Explained
Fractional distillation of crude oil is the process refineries use to separate crude into fractions by boiling point. Crude is heated and enters a tall column, where hydrocarbons condense at different heights. Lighter fractions rise to the top and heavier ones settle lower down, each collected at its own stage.
- Heating and vaporization: crude is heated in a furnace before entering the column
- Column stages: trays collect fractions at set temperatures from top to bottom
- Light fractions: refinery gas, petrol (gasoline) and naphtha boil off near the top
- Middle fractions: kerosene, diesel and gas oil are drawn off at intermediate trays
- Heavy residue: fuel oil, lubricants and bitumen remain at the base
Use this map to revise the order of fractions and their boiling ranges. Create a personalized map from your own notes with CogniGuide to test your recall.
Fractional Distillation Questions
Answers to common questions about crude oil distillation and making your own map.
Why does crude oil separate into fractions?
Crude is a mixture of hydrocarbons with different boiling points. When heated, each component vaporizes at a different temperature and condenses at a different level in the column, which allows the mixture to be separated.
Which fraction has the lowest boiling point?
Refinery gases, such as methane, ethane, propane and butane, have the lowest boiling points. They leave at the very top of the fractionating column.
Which file types can I use to make my map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or an image of your notes. You can also type the topic directly.
Can I turn my distillation map into a quiz?
Yes. Any map can become a quiz to test your recall of fractions and boiling ranges. The free plan allows 5 creations a week.
