Outside an oil refinery, you will find tall fractionating towers...........

Explanation:

And crude oil is separated into its various fractions...........#40-60# #""^@C#, #60-80# #""^@C#, ...........#100-110# #""^@C# #"petroleum ethers."# The more volatile fractions contain the isomeric #C_4-C_6# alkanes and olefins, and the boiling point become larger as the hydrocarbons become longer and larger.
