Abstract
Glycol and amine systems are widely used in both refineries and gas processing plants for the removal of contaminants such as water, hydrogen sulfide and carbon dioxide.  Since the majority of the equipment in these plants is fabricated from carbon steel, and the amines are in aqueous solution, there is a high potential for corrosion.  This paper presents two case histories, one from a TEG dehydration system, and the other from an ADIP plant.  These case histories demonstrate the diverse nature of the causes of corrosion in amine plants and the differing approaches that have to be taken to mitigate gas treating equipment corrosion.
