Metal Mobilization From CO2 Storage Cap-Rocks: Experimental Reactions With Pure CO2 or CO2 SO2 NO
نویسندگان
چکیده
CO 2 geological storage will be needed as part of the transition to lower greenhouse gas emissions. During storage, mobilization metals from minerals formation water via rock reactions may a concern for quality. The sources, behavior, and fate metals, however, are not well understood. Metals in calcite cemented sandstone, feldspar-rich ironstone seal drill cores target site were characterized. reacted with low-salinity pure supercritical or impure SO nitric oxide (NO), under reservoir conditions. Calcite core underwent dissolution chlorite, plagioclase, sulfide alteration. highest concentrations calcium manganese released reaction sandstone seal, lowest mobilized arsenic concentration. Pure resulted dissolution, kaolinite, illite, sulfides corroded. Impure led additional corrosion apatite, pyrite, sphalerite cements. Generally, dissolved iron, lead, zinc, then re-precipitated adsorbed. Calcium, manganese, strontium primarily cement dissolution. Plagioclase was second source strontium, chlorite manganese. Although contained higher reactivity carbonates meant that latter main sources contributing metal concentrations. mineral content cores, injected mixture, had an impact on type concentration released. ubiquitous presence carbonate means this study is applicable understanding potential risk factors quality changes, environmentally regulated both complexes overlying drinking aquifers worldwide.

[1] Deep aquifers are potential long-term storage sites for anthropogenic CO2 emissions. The retention time and environmental safety of the injected CO2 depend on geologic and physical factors and on the chemical reactions between the CO2, the aquifer water, and the host rocks. The pH buffer capacity of the aquifer water and the acid neutralization potential of the host rocks are important fact...
متن کاملGeologic Storage of CO2
Dynamic imaging provides an effective way to integrate previous time-lapse data with current data in order to estimate a current model. We present two methods useful for continuous dynamic reservoir and subsurface monitoring. The first method is a stochastic method for the inversion of geophysical data. It uses the ensemble Kalman filter (EnKF) that we demonstrate using time-lapse surface seism...

Ocean storage of CO2 was proposed by Marchetti as one of greenhouse gas control technologies, where CO2 is captured from flue gas of fossil fuels and injected into deep seafloor below the depth of 3500m to be sequestered from the atmosphere as shown in Fig. 1. In the last decade of the twenties century, there was a great progress in study on the ocean storage. Aya and his colleagues and Nishika...
