Experimental evaluation of in situ CO2-water-rock reactions during CO2 injection in basaltic rocks: Implications for geological CO2 sequestration
[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 کاملCO2 Sequestration in Deep Aquifers
Disposal and long-term sequestration of anthropogenic "greenhouse gases" such as CO2 is a proposed approach to reducing global warming. Deep, regional-scale aquifers in sedimentary basins are possible sites for sequestration, given their ubiquitous nature. We used a mathematical sedimentary basin model, including multiphase flow of CO2, groundwater, and brine, to evaluate residence times in pos...
متن کاملExperimental Investigations of Co2 Laser Cut Quality: a Review
Laser cutting is one of the most widely used thermal energy based non-contact type advance machining process. In recent years, considerable experimental investigations have been carried out aiming at improving laser cutting process performance. This review paper aims at presenting the state of the art in the field of CO2 laser cutting of various engineering materials with special emphasis on ex...
متن کاملGlacial CO2 sequestration
Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Introduction Conclusions References Tables Figures Back Close Full Screen / Esc Abstract Given the magnitude and dynamism of the deep marine carbon reservoir, it is almost certain that past glacial – interglacial fluctuations in atmospheric CO 2 have relied at least in part on changes in the carbon storage ...
متن کاملCoupled Approach to Assess Caprock Deformation Caused by CO2 Injection
This study focuses on a specific problem related to the caprock deformation induced by the injection of CO2 at depth. The adopted methodology includes the development of a mathematical model that incorporates the deformable behaviour of storage media and the flow of two immiscible fluids (CO2 and water) within the aquifers while the surface rock or caprock layer is modelled as a thin plate. Gov...
