Corrosion inhibitor formulation for oil and gas industry
A recently granted patent (Publication Number: US11905604B2) discloses a corrosion inhibitor formulation designed for use in oil and gas applications. The formulation comprises a combination of quaternary ammonium salt, fatty acid methyl ester, viscosity reducing agent, and solubilizing agent. The quaternary ammonium salt includes alkyldimethylbenzylammonium chloride and a compound selected from a specific group, with a defined weight ratio. The fatty acid methyl ester can be sourced from various options like soyabean methyl ester, sunflower oil, and more. The formulation also includes specific viscosity reducing agents and solubilizing agents to enhance its effectiveness.
Moreover, the patent claims that the corrosion inhibitor formulation is suitable for preventing corrosion and removing hydrocarbonaceous deposits in various applications, including fuel storage tanks, vehicles' fuel tanks during transportation, and fuel distribution systems. It is specified to be effective in protecting metallurgies such as carbon steel, copper, brass, lead, and zinc at different operating temperatures and moisture levels. The formulation's dosage range is defined, and its corrosion prevention capabilities are quantified in terms of corrosion current density and inhibition efficiency for different metal types. Additionally, the patent details a process for preparing the corrosion inhibitor formulation, involving specific steps and ingredients to ensure its effectiveness in protecting metal surfaces against corrosion, particularly in downhole applications.
