  • What is fractional distillation in oil refining?
  • Fractional distillation is useful for separating a mixture of substances with narrow differences in boiling points, and is the most important step in the refining process. The oil refining process starts with a fractional distillation column. On the right, you can see several chemical processors that are described in the next section.
  • What components come out of a fractional distillation column?
  • Very few of the components come out of the fractional distillation column ready for market. Many of them must be chemically processed to make other fractions. For example, only 40% of distilled crude oil is gasoline; however, gasoline is one of the major products made by oil companies.

  • How does fractional distillation work?
  • This is how fractional distillation works. The main equipment is a tall cylinder called a fractionator (or fractional distillation column). Inside this column there are many trays, or horizontal plates, all located at different heights. Each tray collects a different fraction when it cools to its own boiling point and condenses.
  • How does oil distillation work?
  • 1 Study this diagram of the oil distillation process. Circle T (true) or F (false) in the description. (1. T / F). When this happens, all the crude oil evaporates and the vapour (or gas) rises through the column (2. T / F). As the vapour goes up the column, the temperature decreases (3. T / F).
  • How can a mixture of liquids be separated by fractional distillation?
  • Because they have different boiling temperatures, they can be separated easily by a process called fractional distillation. The steps of fractional distillation are as follows: You heat the mixture of two or more substances (liquids) with different boiling points to a high temperature.
