METHOD OF PRODUCING KEROSENE FRACTION Russian patent published in 2025 - IPC C10G7/00 C10G7/02 

FIELD: oil refining.

SUBSTANCE: invention relates to oil refining and can be used to produce kerosene fractions. Invention relates to a method of producing a kerosene fraction by distillation of oil at primary processing plants, wherein four gasoline fractions are obtained at the stabilization and secondary distillation unit: a fraction from the beginning of boiling to 70 °C, from 70 °C to 90 °C, from 90 °C to 130 °C and from 130 °C to 180 °C, in the main rectification column, the gasoline fraction is separated with a temperature from the beginning of boiling to 140 °C, and from the gasoline secondary distillation unit a gasoline fraction with a boiling point of 130 °C to 180 °C is additionally introduced into kerosene fraction.

EFFECT: increasing output of kerosene fractions and increasing efficiency of rectification process in the main column.
