FIELD: oil and gas industry.
SUBSTANCE: invention is referred to method for treatment of hydrocarbon fractions from sulphur-containing compounds, wherein hydrocarbon fractions are treated by their mixing with ammonia water, division of the receives mixture into treated hydrocarbon fractions and waste ammonia water, which is regenerated and thereafter supplied again to treatment of hydrocarbon fractions. Regeneration of waste ammonia water is performed by its treatment from sulphur-containing compounds, rectification with produced waste water and gaseous final product sent to scrubber, receipt in the scrubber of treated gaseous ammonia, which is subject to absorption by treated waste water in a reservoir for ammonia absorption with receipt of regenerated ammonia water.
EFFECT: improving ecological safety of hydrocarbon fractions treatment, easy and reliable disposal of waste ammonia water.
