Pitting corrosion of carbon steel in rich diglycolamine solutions from gas sweetening units was investigated using potentiodynamic cyclic anodic polarization. potentiostatic measurements, scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS) techniques. The solution used contained 28000 ppm hydrogen sulfide
