Organic corrosion inhibitors (CI) have widespread use in the crude oil refining industry for corrosion protection and mitigation.¹ An effective corrosion inhibitor is a chemical substance that is applied in low concentration into a stream which suppresses or mitigates a corrosion mechanism.^,2,3,4 Inhibitors can be classified into two classes: adsorption or film-forming with organic inhibitors falling under the adsorption class. In this type of inhibitor a self-assembled structure is formed, where an array of hydrocarbon tails extend away from the metal surface and the polar groups (e.g., N in amines) chemisorb onto the metal surface.² Over the years, certain classes of inhibitors have been established as industry standards to confront specific corrosion mechanisms encountered throughout the refinery process. Examples include, filming and neutralizing amines used in crude units to combat aqueous corrosion; polysulfides used in FCCU to combat hydrogen blistering, cracking and embrittlement; P-based chemistries to combat naphthenic acid corrosion.⁵
