Abstract Scope Injecting H2S scavenger is a common practice to reduce H2S. However, failures in the form of SCC of steel pipes have been reported. However, there is no knowledge about the effects of this chemistry on the corrosion and cracking mechanism of carbon steel. Based on literature related to corrosion in bicarbonate containing environments and the results of this work, it is suggested that SCC is governed by a possible transition from passive to active kinetics. This transition is a complicated function of sour gas concentration and amine adsorption. In this work, in-situ Raman spectroscopy was used to identify the chemical species present in the test solution prior to and following the scavenging process. In-situ surface enhanced Raman spectroscopy and electrochemical techniques were utilized to measure specific adsorption of amine by-products on the steel, as well as, changes in the surface film composition. Finally, ssrt was performed to evaluate SCC susceptibility.
