Introduction to SupPʜʀᴇᴇǫᴄ
This work was partly supported by NSF grant EAR-1926734, the endowment for the Haydn Murray Chair, and the Office of the Vice Provost for Research of Indiana University.
SupPʜʀᴇᴇǫᴄ is an interactive program, developed to link Sᴜᴘᴄʀᴛʙʟ and Pʜʀᴇᴇǫᴄ to facilitate geochemical modeling at temperatures and pressures of interests that is above 25 o C and 1 bar. Such needs arise when one wishes to model geochemical reactions pertinent to clastic and carbonate diagenesis, geological carbon storage, geothermal energy, and igneous and metamorphic processes. David Parkhurst, the author of PHREEQC, has modified the code to accommodate speciation, solubility, reaction path, and coupled reactive transport modeling to 1000 oC and 5000 bars (v.3.6.4). Users would need to wait for David to release the desktop version or temporarily use the online version at https://models.earth.indiana.edu/phreeqc.php.

Fig. 2. T-P range of the bl.dat generated by SUPPHREEQC is restricted by SUPCRTBL and its inherent applicable T-P ranges of HKF EOS. See Johnson et al. (1992) for more details. REGION 1 & 2 covers the T-P range for bl.dat. REGION 3 shows T-P range not applicable by bl.dat. Note the blue dot indicates the critical point of water (373.917 °C and 220.46 bar).
