FIELD: chemistry.
SUBSTANCE: corrosion inhibitor of prolonged action for protection of oil field and oil-refining equipment contains polymer compound - alkyl- and oxyalkylpolyamines, partially quartenised by nitrogen atoms, non-ionogenic suface-active substance and hydrocarbon solvent - monoatomic alcohol CnH2n+1OH, where n=1-4, with the following component ratio, wt %: polymer compound 5-30; SAS low-molecular 5-20, solvent - the remaining part. As surface-active substance for protection against hydrogen sulfide corrosion used is low-molecular quarternary ammonium compound, and for protection against carbonic acid corrosion used is ester of unsaturated dicarboxylic acid and alcohol.
EFFECT: reduction of corrosion rate in aggressive media, containing hydrogen sulfide and carbon dioxide.
