Abstract
The present invention relates to a method for inhibiting high temperature corrosion of corrosion prone metal surfaces by organic acid-containing petroleum streams by providing an effective corrosion-inhibiting amount of an additive aromatic compound tri-substituted with acidic functionalities selected from 5-hydroxyisophthalic acid and 1,3,5-benzenetricarboxylic acid, typically up to 1000 wppm, to the metal surface.
