corrosion

Issues associated with mercury’s presence in hydrocarbon processing systems have become more apparent as deeper and hotter reservoirs (often with higher levels of mercury) were exploited, and with the low-temperature gas processing used for liquefied natural gas (LNG) and natural gas liquids.

This paper presents a methodology to estimate the probability of failure of every individual corrosion defect and the residual likelihood of failure of an overall corroded pipeline segment after selected repairs, using structural probabilistic analysis.

Through a range of experiments the authors demonstrate that small amount of H2S can be beneficial in reducing corrosion in 3% Cr steel.
