During the refining process, when the temperature exceeds 230 ºC, sulfur and cycloalkanoic acid undergo chemical corrosion. Sulfur reacts with Fe to form FeS, which adheres to the metal surface to form a protective film that can prevent further corrosion by sulfur. When there is cyclic acid in the system, it reacts chemically with iron to form surface active cyclic acid iron, which can dissolve the FeS film and promote further corrosion by sulfur. When both coexist in a corrosive environment, corrosion will be more severe. SD-GH type high-temperature corrosion inhibitor is developed for the high-temperature corrosion mechanism of sulfur-containing and acid containing crude oil, combined with the process conditions of the device. The agent has a metal surface modification effect, forming a stable and dense chemical film on the metal surface, thereby preventing the corrosion of sulfur and cyclic acid on the metal and achieving the effect of controlling high-temperature sulfur cyclic acid corrosion. It has neutralization and film-forming functions, forming a stable chemical protective film that is not affected by acidic or alkaline media; It can undergo neutralization reaction with petroleum acid in corrosive media, reducing acidic corrosion. And it can withstand high temperatures of 200-400 ºC.
