Which of the following uses fractional distillation?
Both of the above
When we get water from a natural source, such as underground water or rain water, it contains numerous minerals and impurities. Thus, prior to making its way to store shelves, this type of water is fractionally distilled to remove those impurities/minerals. The end result is the production of distilled water. The same concept applies to the production of gasoline from crude oil.
If we step foot into an oil refinery, we will see multiple pieces of equipment all collectively working to make a variety of products from crude oil. Crude oil is a mixture of numerous organic molecules. By using the concept of boiling point, during the fractional distillation process, oil refinery workers can ensure the compounds of interest are correctly separated from a crude oil mixture.
