Thermodynamic data for reactions involving halite (NaCI) and silicates (& calcite) have been used to calculate the HCI gas concentration in vapor at high temperatures in the presence of a hypersaline brine. Mineral reactions produce as much as 700 pp at 350 "C. Agreement calculations by Haizlip involving hypersaline brine alone (without halite) is very good. High temperatures favor HCI gas and equilibrium concentrations at 250 "C are negligible. The correlation of HCI with high temperature is clear at Larderello and (with less data) at The Geysers.
