Experimental measurement of CO2 solubility in a 1 mol/kgw CaCl2 solution at temperature from 323.15 to 423.15 K and pressure up to 20 MPa
Résumé
Compared to data of CO2 saturation in NaCl aqueous solution, data on the solubility of CO2 in CaCl2 solutions are scarce. In this work, a new analytical method was developed to measure the CO2 solubility in calcium chloride solution. This method relies on conductimetric titration coupled with pH measurement. Saturation data of CO2 in a 1 mol/kgw CaCl2 solution in the pressure range from 1 to 20 MPa and between 323.15 and 423.15 K were acquired
