Solubility of Anhydrite in Supercritical Water from 380 ˚C to 625 ˚C and 220 bar to 270 bar - Rendel et al., 2024

The solubility of anhydrite in deionized water has been determined experimentally from 380 ˚C to 625 ˚C and 220 bar to 270 bar. The experiments were performed using a unique flow-through reactor capable of reaching supercritical conditions for pure water. The results cover the approximate range of temperature and pressure expected to be found in deep geothermal systems where supercritical conditions could be expected. Anhydrite solubility has not been previously well-defined in this region.
