Corrosivity in refinery sour water systems

The subject of alkaline sour water (ammonium bisulphide) corrosion in petroleum refineries has been addressed in the literature over the past 25 years. However, despite the prevalence of sour water corrosion problems in refining operations, very little actual ammonium bisulphide corrosion data are published in the open literature. Surprisingly, most of these studies do not take into account the
