In the oil and gas production environments, the corrosivity of produced water depends on the nature of the dissolved substances. The mitigation of corrosion of carbon steel in the presence of CO2, H2S and elemental sulfur was investigated in this study. Laboratory autoclave tests were conducted to study the efficiency of selected corrosion inhibitors. Based on the laboratory test results, water-soluble organic corrosion inhibitors are found to be effective in controlling corrosion of carbon steel in the presence of CO2, H2S and S.
Key words: corrosion inhibitors, C02 corrosion, H2S and sulfur corrosion, sulfur deposition
