Abstract
The effect of corrosion inhibition by organic inhibitors, mainly 2-aminothiophenol (ATP), (1-hydroxyethylidene)bis(phosphonic acid) (HEDP) and diethanolamine (DEA) for mild steel (JIS SS 41, UNS K02600) and stainless steel (type 304, UNS S30400) in CO 2 absorption process was investigated by corrosion weight loss tests, electrochemical measurements, and surface analysis. The inhibition of iron carbonate (FeCO 3 , scale) formation by inhibitors was also evaluated by X-ray diffraction (XRD) and infrared absorption spectroscopy (IR)
