Gasoline is produced by crude oil fractionation and heavy distillate cracking.
Using crude oil fractionation methods, it is possible to vary the boiling points of the components.
Fractionation of crude oil into straight-run gasoline, light and heavy diesel, kerosene, etc.
Gasoline has the lowest boiling point. After the gasoline vapor is first pumped out and cooled, it is pure liquid gasoline.
