The potentiodynamic polarization curve of carbon steel measured on the each condition was extrapolated to obtain the
corrosion current density and then to calculate the corrosion rate (MPY, mils per year) using Faraday’s law. The corrosion rate
of carbon steel was increased with the temperature of each amine solution from 50℃ to 150℃, maximal at around 150℃,
and decreased with the temperature from 150℃ to 300℃. The corrosion rate of carbon steel was diminished from 8.5 to 10.0
of pH. Under the same temperature and pH conditions, the corrosion rate of carbon steel became increased in order of
3-MPA<ETA<Morph<NH3.
