FIELD: oil and gas industry.
SUBSTANCE: invention relates to a one-stage treatment method of hydrocarbons containing sulphones in one reactor made from nickel alloy. The method involves contact of a flow of hydrocarbons containing sulphones with a water solution of alkali metal hydroxide chosen from a group consisting of sodium hydroxide and potassium hydroxide in a sheet of vertically hanging fibres at the temperature of up to 350°C and at pressure of up to 170 atm, where hydrocarbons and alkali metal hydroxide respond with removal of sulphur atom from sulphone molecule with formation of a water phase saturated with sulphites and a hydrocarbon phase containing less than 10 parts by weight of total sulphur; with that, fibres consist of the material that does not contaminate the reactor and are wetted with one of the two non-mixing liquids.
EFFECT: removal of sulphur from a flow of hydrocarbon fuel without any destruction of the whole structure of a sulphone molecule.
