A corrosion inhibitor composition, which includes (i) a date palm leaves extract, (ii) a benzimidazole compound having at least one a carbamate group, (iii) a pyridine compound, (iv) a thiourea compound, (v) a cinnamaldehyde compound, (vi) a metal iodide, (vii) urotropin, and (viii) a base fluid containing an alcohol and an organic acid. A method of inhibiting corrosion of metal during acid cleaning is also disclosed, whereby the metal is treated with an acidic treatment fluid containing 1 to 5 wt. % of an acid, based on a total weight of the acidic treatment fluid, and 0.1 to 5 vol. % of the corrosion inhibitor composition, based on a total volume of the acidic treatment fluid.

Corrosion inhibitor composition and methods of inhibiting corrosion

Corrosion inhibiting formulations including a substituted benzimidazole, a mercaptocarboxylic acid, a 2-thioxodihydropyrimidine-dione, a sulfhydryl alcohol, a surfactant, and a solvent. Methods for preventing, inhibiting, or reducing metal (e.g. carbon steel) corrosion utilizing these formulations are described. The formulations are effective against corrosion of metallic substrates in sweet (i.e. CO), sour (i.e. HS), and/or high salinity environments commonly found in petroleum industry.
