METHOD OF PRODUCTION OF ACID BACTERICIDE CORROSION INHIBITOR |
摘要 |
FIELD: protection of metals against corrosion in acid and aqueous-salt hydrogen-sulfide-containing media; oil and gas producing industry; metallurgy; power engineering. SUBSTANCE: proposed method includes mixing of nitrogen-containing component, acid and formaldehyde-containing compound; used as nitrogen-containing compounds are primary aliphatic amines of NH2R formula or mixture of primary and secondary aliphatic amines of NHR2 formula, where R is alkyl with number of carbon atoms of C8-C20 or isoalkyl amines containing branched structure of amines of C8-C20 fraction; non-ionogenic surfactant; before mixing, nitrogen-containing compounds is subjected to interaction with acid solution. Proposed method is high efficient for oil media containing sulfate reducing bacteria. EFFECT: enhanced efficiency of corrosion protection. 2 cl, 1 tbl, 23 ex
