Refinery
you use fractional distillation! basically, all the different substances in crude oil have different boiling points, and the column which is used to do fractional distillation has stages with different temperatures. when the substance reaches its boiling point temperature in the column, it turns into liquid and settles there, away from other fuels.

Crude oil can be refined to make a plethora of petroleum product. Kerosene, gasoline, petroleum jelly (commonly known as Vaseline), lubricating oil, and heavy fuel, and many other products. Crude oil contains many different substances which all separate during the refining process.
Comparative: More crude Superlative: Most crude 'Cruder' and 'crudest' are perfectly acceptable, and indeed more idiomatic than 'more crude' and 'most crude'.

A refinery...
That would be a "refinery".
Crude oil is a mixture of compounds called hydrocarbons. Many useful materials can be produced from crude oil. It can be separated into different fractions using fractional distillation, and some of these can be used as fuels. Unfortunately, there are environmental consequences when fossil fuels such as crude oil and its products are used.
After crude oil is removed from the ground, it is sent to a refinery by pipeline, ship, or barge. At a refinery, different parts of the crude oil are separated into usable petroleum products.
This is typically called a refinery.
Petroleum distillates are products made from crude oil. The process of taking crude oil and creating finished products is called distillation. The first step of the refining process is running crude oil through a distillation tower. At this time crude oil is separated into different basic products which then undergo further process at the refinery to create products that are sold to consumers. There are three classes of distillate products: Light: Liquid Petroleum Gas(LPG), gasoline, and naptha. Medium: Kerosene (and jet fuel) and diesel. Heavy/Residuum: Heavy fuel/bunker fuel, wax, and asphalt.
It's called refining the petroleum (occurring at refineries). This process is used in order to separate the crude oil into products such as diesel fuel, heating oil, liquified petroleum gas, kerosene, gasoline, or asphalt base.
"Petroleum" products are distilled from crude oil, so what comes out of the ground is crude oil.
