Crude oil is practically applied. It is subjected to cleaning and processing.
Sometimes the primary and secondary refining.
Primary processing of oil is a distillation, in which the oil is separated into its component parts (called fractions):
- liquefied gas;
- gasoline (road and aviation),
- jet fuel,
- diesel fuel (diesel oil),
- the fuel oil.
The first five types of petroleum products are fuel. And the oil is processed to obtain:
- liquid fuel boiler,
When mixing of bitumen with mineral substances obtained asphalt (asphalt concrete), used as a road surface.
Liquid boiler fuel used to heat homes.
From oil produce a wide range of lubricants:
- lubricating oil;
- insulating oil;
- hydraulic oil;
- cutting fluid;
Oil obtained from crude oil, are for making ointments and creams.
Remaining after the distillation of crude oil concentrate is called tar. He goes on road and building coverage.
Secondary oil processing involves changing the structure of its component hydrocarbons. It provides the raw material from which to get:
- synthetic rubbers and rubber;
- synthetic fabric;
- polymer films (polyethylene, polypropylene);
- solvents, paints and varnishes;
Even the waste oil processing have practical value. From waste oil distillation is coke. It is used in the manufacture of electrodes and in metallurgy. And sulfur which is removed from the oil refining process, is used for the production of sulfuric acid.
Oil gives heat and light
