Abstract: The mechanism of corrosion happened in CO2 absorption by alcohol-amine solution is summed up.It is found that HCO-3,H3O+ and protonated amines are the root causes that the solution has corrosivity.Temperature,type of amine,heat stable salts and CO2 all have impact on the corrosion effect.Adding corrosion inhibitor is the key measurement to inhibit corrosion.Worldwide research and development advances in corrosion inhibitor are summarized,and the future development direction in controlling corrosion in amine solution is also proposed.
