olm.USGS.PhreeqcPandas.findPCO2atCalciteSaturation¶
- olm.USGS.PhreeqcPandas.findPCO2atCalciteSaturation(phreeqcInputFile, PHREEQC_PATH, DATABASE_FILE, newInputFile=None, units='atm')[source]¶
Finds the PCO2 where calcite would be saturated by modifing PCO2 of a PHREEQC input file.
- Parameters:
- phreecInputFilestr
The name of the input file to modify.
- PHREEQC_PATHstring
The path to the PHREEQC executable.
- DATABASE_FILEstring
The database file to be used by PHREEQC.
- newInputFilestring
The name of the set-PCO2 file to create and run. If not specified, the final 5 characters will be stripped off of phreeqcInputFile and ‘set-PCO2.phrq’ will be added.
- units: string
The units in which to return the partial pressure of CO2. Currently, ‘ppm’ and ‘atm’ are allowed (Default=atm).
- Returns
- ——-
- PCO2float
The PCO2 at which calcite would be in equilibrium.
