Abstract
In this work the corrosion rate of UNS(1) K12000 (DIN(2) 17100 ST 52) low-alloy structural steel in monoethanolamine (MEA) solution was studied. The corrosion testing was mainly performed on a rotating disc electrode, and electrochemical impedance was used to estimate the corrosion rate. The parameters studied were rotation rate, influence of oxygen and degradation of the MEA. The results shows a significant increase in the corrosion rate when oxygen was introduced to the system, especially when the rotation rate was high. The corrosion also increased when the MEA solution was degraded. © 2016 by NACE International.
