| 中文摘要: |
| 目的 探明超临界CO2/H2O介质环境下缓蚀剂的作用机制，并筛选可靠的缓蚀剂。方法 采用高压电化学测试、动态质量损失测试和表面形貌分析等手段，研究月桂酸对N80碳钢在不同CO2压力条件下的缓蚀行为变化。结果 月桂酸是一种混合型缓蚀剂，能显著抑制碳钢在超临界CO2/H2O环境下的腐蚀。结论 当体系由非超临界CO2状态转变为超临界CO2状态时，月桂酸在碳钢表面覆盖膜更为致密，且具有显著的疏水作用，缓蚀效率得到明显提升。 |
| 英文摘要: |
| The work aims to find out the action mechanism of corrosion inhibitor in supercritical CO2/H2O medium and select reliable corrosion inhibitor. Corrosion inhibition performance of lauric acid on carbon steel in supercritical CO2 was investigated by electrochemical measurements, dynamic weight loss tests and surface morphology analysis. Lauric acid was a mixed-type corrosion inhibitor and could effectively protect carbon steel from CO2 corrosion. When the system changes from non-supercritical CO2 state to supercritical CO2 state, the film of lauric acid on the surface of carbon steel is denser and has obvious hydrophobic effect, and the corrosion inhibition efficiency is obviously improved. |
