Geochemical impact of aquifer storage for impure CO2 containing O2 and N2: Tongliao field experiment

Wei, Ning; Li, Xiaochun; Wang, Yan; Zhu, Qianlin; Liu, … - In: Applied Energy 145 (2015) C, pp. 198-210

Impurities such as N2 and O2 can be co-injected with CO2 to cut the overall cost of carbon capture and geological storage by lowering the CO2 capture cost. However, only few field-scale studies have focused on the effect of these impurities, such as N2 and O2, with low solubility and a low...
