A corrosion inhibitor composition, which includes i) an aqueous alcohol base fluid, ii) a mixture of at least three polysaccharides selected from carboxymethyl cellulose, gum arabic, pectin, a salt of alginic acid, chitosan, dextran, hydroxyethyl cellulose, and soluble starch, with each polysaccharide that is present in the mixture being present in an amount of 0.05 to 0.5 wt. %, based on a total weight of the corrosion inhibitor composition, iii) silver nanoparticles, and iv) a pineapple leaves extract. A method of inhibiting corrosion of metal during acid cleaning/pickling whereby the metal is treated with an acidic treatment fluid containing an acid and the corrosion inhibitor composition.

Method for inhibiting metal corrosion during acid cleaning or pickling

The present invention relates to a method of inhibiting corrosion of steel in contact with a corrosive solution. The method involves mixing an olive leaf extract titanium nanocomposite with the corrosive solution. The olive leaf extract titanium nanocomposite may be made by reducing TiClwith an olive leaf extract, which forms nanoparticles with an average size of 50-100 nm.

Biomediated-titanium nanocomposite for corrosion protection

Corrosion inhibitor composition and methods of inhibiting corrosion during acid pickling

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 compositions and methods of inhibiting corrosion on a metal surface commonly used in the petroleum industry is disclosed. The corrosion inhibitor includes at least one azole, at least one polypeptide derived from amino acid, at least one intensifier preferably from metal halides, and at least one surfactant. The methods include combining effective amounts of the corrosion inhibitor composition and contacting a metal surface in aqueous environment commonly found in oil and gas industry. The composition is very effective against corrosion of metals in contact with aqueous media when used in a dosage as low as 50 ppm.
