摘要:

研究了油气输送管道中常用的两种碳钢C75和X65及3种不锈钢13Cr,2205和904 L在80 ℃,12 MPa含有不同浓度O₂的超临界CO₂环境中的腐蚀行为。结果表明,当超临界CO₂中O₂浓度较低时,即使是微量O₂ (1.50×10^-⁶),也能显著地加速碳钢和13Cr不锈钢的腐蚀；在O₂浓度很高时 (5.70×10^-²) 出现钝化现象,与不含O₂时相比,无论碳钢还是13Cr不锈钢的腐蚀速率均降低；2205和904 L不锈钢的腐蚀均不受O₂浓度的影响。

Abstract：

The carbon capture and storage (CCS) in geological reservoirs is now considered to be one of the main options for achieving deep reductions in CO₂ emissions. Generally, the purity of captured CO₂ is only about 95% and can contain trace gases such as O₂, CO, SO_x and NO_x. In the presence of a water phase, these trace gases can contribute to the corrosiveness of high pressure-high temperature CO₂ (supercritical CO₂) systems. In this study, corrosion experiments of supercritical CO₂ with various amounts of O₂ were carried out to study the effect of small concentrations of O₂ on the corrosion rate of two kinds of carbon steels C75 and X65 and three kinds of stainless steels 13Cr, 2205 and 904L in aqueous supercritical CO₂ at 80 ℃ under 12 MPa. The decay kinetics of small starting O₂ concentrations were investigated and used for the experiments with continuous replenishment of used-up O₂. The results indicated that constant O₂ concentrations in supercritical CO₂, even trace of O₂ (1.50×10^-⁶), could enhance the corrosion rate of carbon steels tremendously (more than 100 mm/a). Under this condition, even the corrosion rate of 13Cr stainless steel obviously increased. However, surprisingly, with high O₂ concentrations seemed to exhibit passivation effect and the corrosion rates for carbon steels and 13Cr stainless steel were relatively low. The 2205 and 904L stainless steels were unaffected by addition of O₂ and showed high resistance (<0.01 mm/a) to the aqueous supercritical CO₂ corrosion.

Key words： supercritical CO₂ O₂ carbon steel stainless steel corrosion rate
