Factors In Galvanic Corrosion Between Steel And Iron Sulfides In Acidic Solutions

Product Number: 51322-17827-SG

H2S corrosion, also known as sour corrosion, is one of the most researched types of metal degradation in oil and gas transmission pipelines requiring a wide range of environmental conditions and detailed surface analysis techniques. This is because localized or pitting corrosion is known to be the main type of corrosion failure in sour environments which caused 12% of all oilfield corrosion incidents according to a report from 1996. Therefore, control and reduction of this type of corrosion could prevent such failures in oil and gas industries, and significantly enhance asset integrity while reducing maintenance costs as well as eliminating environmental damage.

Dewpoint corrosion is a well-known phenomenon in flue gas stacks and refinery overheads, where fine water droplets condense from the vapor upon cooling, and the acid gases in the vapors diffuse into water droplets to form a highly corrosive low pH liquid. We have identified a similar mechanism in hydrocarbon liquids, which we call as “nucleation corrosion” (C2023-19463). Liquid hydrocarbons often have dissolved water (DW), which does not promote corrosion even in the presence of corrosive species (e.g., organic acids, H2S). Upon cooling, the DW nucleates as nanometer-sized water droplets and acids present in the liquid partition into the water droplets decreasing pH to cause aggressive nucleation corrosion. In this study the methods to mitigate nucleation corrosion are investigated with an emphasis on studying the impact of different types of chemical inhibitors on this newly discovered mechanism. An interesting example of the impact of the test method on inhibitor selection is shown. Finally, a case study highlighting nucleation corrosion in a refinery distillation overhead reflux line is presented.

Nucleation Corrosion in Liquid Hydrocarbons

Product Number: 51323-19463-SG

The condensation of acidic species from vapor to liquid occurs when the system is cooled to or below the dew point temperature. Such condensation leads to extremely aggressive corrosion that is referred to as acid dew point corrosion. Some also refer to this corrosion as low temperature corrosion or cold corrosion.
