FIELD: oil and gas industry.
SUBSTANCE: invention relates to a method of purifying hydrogen sulphide-containing oil and can be used in the gas and oil industry. Method of purifying hydrogen sulphide-containing oil involves oxidation of hydrogen sulphide in the presence of a catalyst solution of cobalt phthalocyanine derivatives in 20–30% aqueous ammonia solution at temperature of 20–70 °C and overpressure. Hydrogen sulphide oxidant used is an oxygen-air mixture with oxygen concentration of not less than 62 vol.%. Oxygen-air mixture is fed into the flow of hydrogen sulphide-containing oil at least in two portions along the length of the pipeline.
EFFECT: invention allows increase output of commercial oil.
