OIL REFINING METHOD Russian patent published in 2013 - IPC C10G7/00 C10G65/04 C10G69/06 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to refining and petrochemical industries. Invention refers to oil refining method that includes fractionating of oil with extraction of gasoline fraction, light and heavy gasoil cuts and residue, thermal conversion of heavy gasoil cuts with obtainment of heavy residue of thermal conversion, gasoline fraction and light gasoil cut of thermal conversion, hydrofining of total amount of light gasoil cuts and gasoline fractions with obtainment of respective hydrogenation products and stabilisation of hydrogenation products of total light gasoil cuts with production of diesel fuel. Heavy gasoil cut is premixed with refined oil and sum of residues of fractionating and thermal conversion mixed with fraction of aromatic hydrocarbons C₉₊ are subject to hydroconversion with obtainment of hydrogenation products divided into gasoline fraction and light gasoil cut and residue outputted as fuel oil for auxiliaries; at that hydrogenation products of the sum of gasoline fractions of fractioning, thermal conversion and hydroconversion are subject to reforming and subdivision of reforming products into aromatic hydrocarbons and refined oil while aromatic hydrocarbons are divided into benzene, toluene, xylene and fraction of aromatic hydrocarbons C₉₊; at that the sum of light gasoil cuts of fractioning, thermal conversion and hydroconversion are directed to hydrofining.

EFFECT: increasing productivity and diversification of refined products, increasing yield of diesel fuel.
