Resum
Injection of CO2 at depth will cause the acidification of groundwater. As a preliminary study for the potential use of MgO as an alternative to Portland cement in injection wells, MgO carbonation has been studied by means of stirred batch experiments under subcritic (pCO(2) of 10 and 50 bar and T of 25, 70 and 90 degrees C) and supercritic (pCO(2) of 74 bar and T of 70 and 90 degrees C) CO2 conditions.; Magnesium oxide reacts with CO2-containing and Ca-rich water nearly equilibrated with respect...
