Carbon dioxide may induce corrosion on the piping steels during compression, transportation and injection. Therefore, selection of appropriate piping steels is a key factor in order to increase the safety and reliability of the CCS technology, and to keep the processes cost-effective. The here described subproject of the COORAL project (German acronym for “C02 purity for capture and storage”) deals with the levels of impurities in the C02 stream that will be acceptable when using specific steels. Material exposure to carbon dioxide (C02) containing specific amounts of water vapor, oxygen (02) sulfur dioxide (S02), nitrogen dioxide (N02), carbon monoxide (CO) can be a challenge to steels. Within this subproject 13 different Steels are tested for suitability as materials used for compression, transportation and injection Units within the CCS chain.

T1 - Corrosion behavior of highly alloyed steels in artificial saline aquifer fluids containing carbon dioxide N2 - C02-corrosion on piping steels might cause problems during injection of flue gases for their storage in deep geological aquifer fluids. Therefore, the selection of appropriate piping steels is a key factor to increase safety and reliability of the Carbon Capture and Storage (CCS) technology, and to keep the process cost-efficient. Within the project COORAL (German acronym for “C02 purity for capture and storage”) corrosion studies on injection piping steels exposed to C02 and artificial brine with high Chloride concentration have been carried out. Corrosion of the injection pipe in C02-rich aquifer fluid may occur within the aquifer brine or when at injection interruptions the aquifer fluid may flow back into the injection pipe. Because of high salinity of aquifer brine and C02-corrosion an appropriate material ranking of injection piping steels should be made. Corrosion resistance of steels 1.4034, 1.4021, 1.4542, 1.4162 and 1.4562 was investigated in a corrosive environment using electrochemical and metallographic techniques. Electrochemical experiments in order to investigate the surface corrosion kinetics and polarization measurements in order to investigate localized corrosion phenomena have been carried out. Critical pitting potentials and repassivation potentials were determined by polarization curves of investigated materials and compared with measured corrosion potentials. Measured values were used in order to determine the suitability and performance of tested steels in C02-injection conditions.

A1 - Kranzmann, Axel T1 - Corrosion behavior of steels for CO2 injection N2 - The process chain for Carbon Capture and Sequestration (CCS) includes tubing for injection of CO2 into saline aquifers. The compressed CO2 is likely to contain specific impurities; small concentrations of SO2 and NO2 in combination with oxygen and humidity are most harmful. In addition, CO2 saturated brine is supposed to rise in the well when the injection process is interrupted. The material selection has to ensure that neither CO2 nor brine or a combination of both will leak out of the inner tubing. In this comprehensive paper the investigated materials range from low-alloy steels and 13% Cr steels up to high-alloy materials. Electrochemical tests as well as long term exposure tests were performed in CO2, in brine and combination of both; pressure was up to 100 bar, temperature up to 60 °C. Whereas the CO2 stream itself can be handled using low alloy steels, combinations of CO2 and brine require more resistant materials to control the strong tendency to pitting corrosion. The corrosion behavior of heat-treated steels depends on factors such as microstructure and carbon content. For different sections of the injection tube, appropriate materials should be used to guarantee safety and consider cost effectiveness.

Because of their acidic origin the corrosion resistance of pipeline steels used for CCS (carbon capture and storage) technology might be limited. Over the last years it has become clear that the amount of water and acid building constituents in the CO2 stream has to be controlled very well. In this work, condensates formed in experiments using gaseous CO2 containing high amounts of water, NO2 and SO2 were analyzed, replicated, and used for extensive electrochemical experiments. These highly acidic condensates were enriched with CO2 and then applied to characteristic steels planned to use in the CCS transport chain. Even high alloy steels are susceptible to localized corrosion under these conditions. The results implicate that condensation of aggressive acid droplets has to be avoided or the locations where condensation takes place have to be controlled extensively.
