Gas Processing plants consists of several critical operating units and the operational reliability of each unit has a direct impact on entire plant’s operation. In general the material selection aspect plays a crucial role in determining the equipment reliability which heavily depends on the mode of operation.More than three decades of operational experience in gas processing plants of Saudi Aramco revealed that the metallurgy selected at the initial design provided satisfactory performance. However several components and equipment made of carbon steel experienced accelerated localized deterioration with erosion-corrosion preferential weld attack being the predominant damage mechanisms.Due to complexity associated with the varying feed rate coupled with other factors such as solids filtration aging gas composition chemical and thermal degradation proactive corrosion management remains a challenging task. This paper focuses on case history root cause analysis and ongoing efforts to restore operational reliability.
