Kinetics of Chlorite Dissolution at Elevated Temperatures and CO2 Conditions
Methods and results of the Kinetics of Chlorite Dissolution at Elevated Temperatures and CO2 Conditions are described and discussed in the paper. Data from this experiment is included as a downloadable .xlsx spreadsheet in the linked GDR submission.
Chlorite dissolution kinetics were measured under far from equilibrium conditions using a mixed-flow reactor over temperatures of 100-275 degrees C at pH values of 3.0-5.7 in a background solution matrix of 0.05 m NaCl. Over this temperature range, magnesium was released congruently with respect to silica. The effect of variable pCO2 levels representative of engineered geothermal systems with CO2 as a heat-exchanging fluid (CO2-EGS) was explored by reacting chlorite with solutions containing a range of dissolved CO2 concentrations (0.1-0.5 M).
