- W1987373321 abstract "Abstract In planning for large-scale CO 2 capture procedures, there exists an economic incentive to leave minor gas components in the captured CO 2 stream for geological storage, because doing so would reduce the cost of the capture process. However, co-injection of reactive impurities (such as O 2 , CO, H 2 , NOx, and SOx) may have detrimental effects on well injectivity, wellbore integrity, seal performance, and gas–brine–rock interactions. In this study we investigated, using a series of autoclave experiments, the potential impact of O 2 as an impurity on geochemical reactions. Three sandstones were tested: Miocene sandstone (Texas offshore, USA), lower Tuscaloosa sandstone (Cranfield field, Mississippi, USA) and Cardium sandstone (Pembina field, Alberta, Canada). Samples were subjected to reaction with 1.88 M NaCl solution and CO 2 , with and without the addition of a small volume of O 2 in order to determine the geochemical effects of O 2 . A total of ten reaction experiments were conducted at 200 bar and 70 °C or 100 °C. Overall, for rock samples lacking reducing minerals, co-injection of a small volume of O 2 with supercritical CO 2 showed only a limited geochemical impact compared to the reactions with pure CO 2 . The presence of O 2 did not accelerate the dissolution of carbonate and feldspar minerals, nor did it alter the reaction pathways. However, the small amount of pyrite (≈0.7%) contained in the Cardium sandstone had an important impact. As it was oxidized, the solution pH was further lowered because the Cardium sandstone contains little pH-buffering carbonate and feldspar minerals. Consequently, dissolution of carbonates and feldspars was enhanced by the more-acidic solution. Aqueous ferrous iron was largely converted to iron oxyhydroxides and precipitated on mineral surfaces. The minor cations that showed the largest increases in aqueous concentration (such as Mn, Sr, and Ba) were mostly mobilized from carbonates and were not significantly enhanced by O 2 for the low-pyrite sandstones. Releases of trace metals, with the exception of Zn and Pb, were not enhanced by the presence of O 2 . In fact, concentrations of As, V, Mo, and other oxyanions were lower in the reactions involving O 2 than in the pure CO 2 reactions, because these metals sorb on the newly precipitated iron oxyhydroxides." @default.
