  • Patent number: 11286571
    Abstract: The present invention relates to development of high performing oil soluble and water dispersible corrosion inhibitor composition for mitigating internal corrosion of crude oil pipelines during storage and transportation of crude oils. The developed composition consists of acid-amine complex as corrosion inhibiting agent, mixture of organic acids as dispersing agent and ester derivative of alkylated phenol for better film formation. The present invention further relates to a process of preparation of the oil soluble and water dispersible corrosion inhibitor composition and subsequently a process for protecting the corrosion of internal metal surface of crude oil transportation pipelines using the corrosion inhibitor composition.

  • Patent number: 6489272
    Abstract: A composition useful as a well lubricant, solvent, emulsifier, and performance extender for corrosion inhibitors in high velocity gas, oil or water drilling, production or gathering applications, that is preferably formed by the reaction and distillation of a tall oil fatty acid with a fatty alkanolamide, preferably in the presence of methyl ester of fatty acids, and most preferably when further reacted and distilled with an emulsifier such as coconut oil diethanolamide or distilled tall oil amide of aminoethylpiperazine. The fatty acids and oils useful in the invention can range from C8 to C24, with C12, C14, C16, C18 and C20 fatty acids and oils being most preferred. The presence of methyl ester is preferred because it functions as a foam suppressant, diluent and amine scavenger during distillation.
