Crude oil is almost never used. It is subjected to cleaning and processing. There is a primary and
secondary processing of oil.

Primary oil refining is distillation, as a result of which petroleum products are divided into its constituent
liquefied gas;
– gasoline (automobile and aviation);
jet fuel;
– diesel fuel (diesel fuel);
The first five types of petroleum products are fuel. And fuel oil is processed to obtain:
– bitumen;
– liquid boiler fuel;

When bitumen is mixed with mineral substances, asphalt (asphalt concrete) is obtained, which is used as
a road surface.

Oil produces a wide range of lubricants: lubricating oil, electrical insulating oil, hydraulic oil, grease,
coolant, liquid, petroleum jelly. Oils derived from petroleum, go to the preparation of ointments and

The concentrate remaining after the distillation of oil is called tar. He goes to the road and building
surfaces. Secondary oil refining includes changing the structure of its components – hydrocarbons. She
gives the raw material from which they receive:
– synthetic rubbers and rubber;
– synthetic fabrics;
– plastics;
-polymer films (polyethylene, polypropylene);
– solvents, paints and varnishes, dyes;
– fertilizers;
– chemicals;
