pH稳定剂抑制管道潮湿CO_2腐蚀的研究进展

Research Progress in pH Stabilizers for Control of Wet CO_2 Corrosion of Pipelines

加注pH稳定剂是抑制碳钢海底管线潮湿CO_2腐蚀的有效措施,在国外深水气田已经获得成功应用,而国内相关研究工作刚刚开展。本文综述了pH稳定剂的国外应用现状、围绕pH稳定剂展开的评价试验以及pH稳定剂抑制潮湿CO_2腐蚀的机理,为pH稳定剂的研究和应用提供参考。

Addition of pH stabilizers into subsea pipelines is an effective way to control the wet CO2 corrosion in the pipelines. The pH stabilizers have been successfully applied to some deepwater gas fields abroad, while in China the related research just begins. The application status in foreign countries, the evaluation test results and the mechanism of pH stabilizer against CO2 corroion are reviewed. The article may be helpful to the further research and application of pH stabilizers.
