Study of the influence of hydrogen sulphide on steel St3 in the operating environment of oil production

Annotation

Studied the protective effect of the inhibitor “INCORGAZ-IC-31” as inhibitor of hydrogen sulfide corrosion of steel in the environment NACE. “INCORGAZ-IC-31”, is an oily liquid, poorly soluble in water, but soluble in organic solvents. The inhibitor was injected in different concentrations into the test medium. Shown the effect of the inhibitor on the corrosion rate at different concentrations of hydrogen sulfide. Generalized approach to assessing the effectiveness of the inhibitor “INCORGAZ-IC-31”.

Keywords

hydrogen sulfide corrosion; steel; “INCORGAZ-IC-31”; inhibitor
