Corrosion inhibition and monitoring in sea gas pipeline systems
Twenty-eight pipeline corrosion inhibitors were screen-tested in the laboratory under carbon dioxide and oxygen environments to select the most qualified and effective corrosion inhibitor for the pipeline. The inhibitor's ''gunk-forming'' tendency and properties of its condensed form were studied to minimize downstream problems and the inhibitor's adverse effects. An amine-based inhibitor, especially when it has an amide combination, was found to be effective and to show fewer side effects at low oxygen concentration. Inhibitors that are acidic in nature tended to hydrolize in the condensed form and caused stress cracking and pitting problems in the laboratory tests or pipelines. Some of these acidic inhibitors were effective as an oxygen corrosion inhibitor.
