High-temperature polymeric corrosion inhibitors

Corrosion at high temperature is a huge challenging issue that occurs mostly in oil and gas industries. Polymer compounds have been found an effective class of inhibitors to control metallic corrosion at high temperatures. Because most of the polymers are thermally stable as well as have large number of functional groups that can help them easily adsorption on metallic surfaces and mitigate corrosion reactions. Polymer has larger hydrocarbon chain, which makes it additional effective by repelling the corrosive ions from the metallic surface. The present chapter discusses the polymeric corrosion inhibitor at high temperature corrosive environments: acidizing, sweat and sour corrosion, and naphthenic acids as well as computational studies of polymeric corrosion inhibitors.
