FIELD: oil and gas industry.
SUBSTANCE: invention discloses a method for obtaining a low-viscosity marine fuel by atmospheric vacuum distillation of oil with separation of fractions, catalytic cracking of vacuum gas oil, compounding said fractions, characterised in that during atmospheric vacuum distillation of oil a vacuum diesel fraction is recovered in a vacuum column, during atmospheric vacuum distillation of gas condensate – heavy diesel fraction is recovered in the rectifying column and NK-360 °C, which is the upper circulating irrigation of the vacuum column, followed by mixing said fractions with vacuum gas oil of a viscosity breaking unit in a weight ratio of 40:20:40:0–85:5:5:5 and hydrotreatment to obtain a low-viscosity marine fuel, then hydrotreated vacuum gas oil is subjected to catalytic cracking, with separation of the light gas oil fraction from the obtained product and compounding thereof with a low-viscosity marine fuel component in a weight ratio of 90:10–50:50.
EFFECT: technical result is improved environmental, operational, anticorrosion and low-temperature properties.
