METHOD OF OIL REFINING Russian patent published in 2018 - IPC C10G65/12 C10G65/14 C10L1/04 C10L1/10 C10G65/02 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to petroleum refining processes, in particular to methods for processing petroleum in order to produce kerosene and diesel fuel. Method of oil refining involves distilling oil to produce kerosene and separating the straight-run fractions of light and heavy diesel fuel, catalytic hydrotreatment of straight-line fractions of light and heavy diesel fuel, dewaxing of the fraction of heavy diesel fuel, compounding of fractions, addition of additives, obtaining commercial winter diesel fuel, while the straight-legged fraction of light diesel fuel is recovered with a boiling point of 230–290 °C, dewaxing of the fraction of heavy diesel fuel is conducted until a cloud point of minus 26–30 °C, and in the compounding of fractions additionally introduce diesel fractions of hydrocracking, boiling in the range 220–360 °C.

EFFECT: method makes it possible to increase the yield of valuable kerosene and winter diesel fuel.
