In any operating facility, the integrity of flare or relief lines should always be closely maintained, as it is one of the most important safeguards during plant upsets or emergency conditions. The most common damage mechanism in acid flare lines is acid gas dew point corrosion”. Corrosion in such systems is often dependent on fluid stagnation, especially in the presence of acidic water, during idle conditions.
The intent of this paper is to shed light on the efforts done in a gas treatment facility to identify different root causes that impacted or accelerated Acid Gas Dew Point Corrosion. These included design deficiencies, equipment integrity, and process challenges. Moreover, the paper provides findings and recommendations to avoid the occurrence of similar events in acid flare lines.

Proactive Corrosion Control Assessment to Treat Higher-Acidity Gas

Product Number: 51324-20773-SG

Prior to commissioning of a new gas treatment plant, geotechnical analysis showed significant increase in the acidity levels of the feed. Therefore, on-site proactive corrosion control assessment was performed to enable processing higher-acidity gas safely without impacting project schedule. The corrosiveness level of the new feed was re-evaluated in terms of the new required operating conditions. The dominant corrosion damage mechanisms were identified based on the new levels of Hydrogen Sulfide and Carbon Dioxide. Industrial standards and engineering practices were utilized to determine the potential impact on assets integrity. Top corrosion challenges that could be driven up by the increase in acid gas levels were proactively identified. Potential risks in the inlet and gas sweetening facilities were assessed, including the possibility of developing accelerated corrosion at the amine contactor and regenerator columns. The material endurance for the higher operating conditions, temperature and pressure, was evaluated. Further, different inspection techniques were utilized to validate the study results and findings. The inspection methods that were used to analyze and assess the amine contactor and regenerator columns are the On-Stream Inspection (OSI) using the External Ultrasonic Testing (UT) and Visual Examination of the internal surface of the equipment during the turnaround interval. Moreover, process and corrosion simulations of anticipated acid gas and water levels were performed to evaluate the need for advanced corrosion control and inspection measures. Based on that, an effective corrosion control strategy was established including different integrated mitigation measures to ensure assets integrity throughout their full-life cycle.
