Online corrosion monitoring in a postcombustion CO2 capture pilot plant and its relation to solvent degradation and ammonia emissions

Corrosion in amine treating plants is known to cause integrity failures, plant shutdown, costly repairs, and so forth. The use of an amine treatment system for postcombustion CO2 capture brings additional challenges in terms of the flue gas quality, flue gas composition, operating conditions, scale of operation, and so forth. These differences...

Plant applications of online corrosion monitoring: CO2 capture amine plant case study

Over the past several years, there has been a significant effort to bring corrosion monitoring into the realm of online, real-time management with plant process control technology. As part of this new direction in corrosion monitoring, corrosion data (e.g. information on corrosion rate, measured Stern Geary constant (or B value), and parameters...

Ship ballast tanks a review from microbial corrosion and electrochemical point of view

Microbiologically Influenced Corrosion (MIC) is the term used for the phenomenon in which corrosion is initiated and/or accelerated by the activities of microorganisms. MIC is a very serious problem for the ship industry as it reduces structural lifetime in combination with safety risks for crewmembers or inspection personal and increases...

Corrosion monitoring for underground and submerged concrete structures - examples and interpretation issues

Since about 1980 Corrosion Monitoring Systems have been used in many concrete structures in aggressive environmentworldwide. While these systemswork properly in aboveground environment, some questions have arisen for submerged conditions, e.g. the outer sides of tunnels, piers in seawater or foundations in wet soil. One question concerns macro...

Prevention of reinforcement corrosion by hydrophobic treatment of concrete

Corrosion of reinforcement in concrete bridge decks may occur due to penetration of de-icing salts, even in the presence of an asphalt overlay. This paper reports a laboratory study into additional protection of concrete by hydrophobic treatment. It was found that hydrophobic treatment strongly reduces chloride ingress, both during semi...
