FIELD: oil and gas production.
SUBSTANCE: invention refers to procedure for refinement of black oil and oil fractions of components of black oil from hydrogen sulphide. The procedure consists in blowing them with gas at temperature as high, as 80°C. Also, the process is carried out in a mass-transfer unit equipped with contact devices at number of 1-20 perfect plates where there is supplied counter flow: of refined components to an upper part of the unit, and of purge gas - under contact devices of the unit. Inert gas, or hydrogen, or hydrocarbon gases of primary oil refining are used as purge gas. The process is carried out at pressure 0-3 at and at temperature not exceeding temperature of commencement of decay of sulphuric compounds of purified fractions with volume ratio: purge gas: raw stock 1 - 25: 1.
EFFECT: production of commodity black oil with contents of hydrogen sulphide not exceeding 2 ppm.
