A process by which components in a chemical mixture
are separated according to their different boiling points
from a boiling solution
are passed along a column. The temperature of the column gradually decreases along its length. Components with a higher boiling points
condense on the column and return to the solution
; components with a lower boiling points
pass through the column and are collected.
Gasoline is produced from crude oil using fractional distillation.
