FIELD: chemistry.
SUBSTANCE: method of cleaning hydrocarbon media from H2S and/or mercaptans, comprising treating them with a composition comprising an aqueous solution of nitrites of alkali metals and the organic base, wherein the process is carried out in the presence of N-methylmorpholine of N-oxide, nitrite of sodium and/or potassium is used as nitrites of alkali metals, water-soluble aliphatic amine and/or polyamine is used as an organic base, wherein the cleaning process is carried out in the absence of oxygen.
EFFECT: intensification of processes for neutralizing hydrogen sulphide and mercaptans in the absence of air oxygen and limited time for cleaning, reducing corrosion of equipment and pipelines, increasing work safety and environmental safety in the fields.
