The scope of this paper is to discuss the challenges encountered in integrity management of a Quench Column against internal corrosion caused by sour water in a gas plant. The scope also covers many repair techniques and methodologies adopted to maintain the integrity of the equipment without plant / unit shutdown thereby achieving improved reliability of the plant.The information provided in this paper is related to Sulphur unit equipment in a gas plant dealing with sour environments and is useful in taking preventive approach for safe and reliable operation of LNG facilities to minimize volumetric downtime. The case study presented has valuable application in sulphur recovery units with respect to internal corrosion of different columns.Process equipment and associated piping systems in sour service often experience deterioration due to severe operating conditions. Failures can often become the source of major incident risk and therefore timely corrective actions with process modifications corrosion monitoring / permanent and temporary repairs on equipment and piping to suit current conditions are crucial to ensure Plant’s safety and reliability.This paper highlights the failure mechanisms in sour environments vs corrective actions and various integrity management approaches used to overcome practical difficulties to ensure integrity of equipment and enable proper planning to avoid / minimize costly shutdown of the equipment / plant.
