Effect of organic acid on CO{sub 2} corrosion of carbon and Cr bearing steels
Abstract
The effect of organic acid on CO{sub 2} corrosion of carbon and Cr bearing steels was investigated. Acetic acid was considered as the organic acid. The temperature(T{sub max}), which gave a maximum corrosion rate, was observed on pure iron, and 1 and 2%Cr steels in the CO{sub 2} environment with 0.5% CH{sub 3}COOH as well as in the CO{sub 2} environment without CH{sub 3}COOH. The corrosion rate of these steels at T{sub max} extremely increased due to the addition of 0.5% CH{sub 3}COOH, but the T{sub max} did not change. In 9 and 13% Cr steels, the T{sub max} was observed in the CO{sub 2} environment without CH{sub 3}COOH, but did not in the CO{sub 2} environment with 5% CH{sub 3}COOH, and those corrosion rates continued to increase at the temperature above the T{sub max} in the CO{sub 2} environment without CH{sub 3}COOH. These corrosion behaviors were discussed from a viewpoint of pH and FeCO{sub 3} formation condition which was led from the calculated-equilibrium volubility of FeCO{sub 3} at elevated temperatures. Then, those were related to the acceleration of corrosion at the steel surface with heterogeneous FeCO{sub 3} film in pure iron, and 1 and 2% Cr steels, and themore »
