Patent number: 11718918Abstract: 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.Type: GrantFiled: June 15, 2022Date of Patent: August 8, 2023Assignee: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALSInventors: Moses M. Solomon, Saviour A. Umoren

Patent number: 11466210Abstract: 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 TiCl4 with an olive leaf extract, which forms nanoparticles with an average size of 50-100 nm.Type: GrantFiled: July 18, 2019Date of Patent: October 11, 2022Assignee: King Fahd University of Petroleum and MineralsInventors: Saviour A. Umoren, Doga Kavaz, Edidiong A. Essien, Moses Monday Solomon
