Corrosion in alkanolamine gas treatment plants results in unscheduled downtime, production losses, reduced equipment life and even injury or death. Although it is virtually impossible to eliminate, it can be controlled and minimized. Design engineers and plant operators must understand how corrosion affects an amine plant. Some key areas on which to focus are: corrosion mechanisms, different corrosion types, corrosion-contributing factors and preventive measures. Designers can emphasize preventive measures with design considerations, operating parameters and solvent choice. Diagnosing the correct type(s) of corrosion that occur in amine systems is half of the problem. This simple review outlines the various corrosion types for alkanolamine processes and the conditions that frequently occur. Once one has determined the corrosion problem, the preventive design suggestions remedy most plant problems.
