Abstract

Natural hydrothermal fluids very often contain carbon dioxide and chloride ions. Thus the investigation of the systems H2O-CO2 and H2O-CO2-NaCl is fundamental to the understanding of the chemistry of many geothermal systems. The knowledge of the phase behavior and of the activity coefficients of such systems gives more insight into the interaction of rocks with hydrothermal fluids and the deposition of minerals at elevated temperatures and pressures.
