Asset integrity of equipment pressure boundaries is a primary concern in the oil and gas industry. However, certain areas within process plants are susceptible to insidious corrosion mechanisms that can compromise assets over time, requiring periodic monitoring and intervention.
The tail gas unit incinerator stack was observed to be severely affected by a corrosion phenomenon known as dew point corrosion. When the fireside metal surface temperature dropped below the dew point of the flue gases, the highly acidic environment between the refractory and metal caused accelerated corrosion of the metal surface.
In this paper, the authors share their recent experience on a wider knowledge sharing platform on the deleterious effect of dew point corrosion, which warranted extensive repairs of the equipment for further continued operation.
