 In *co2flash.txt*, we define the CO :sub:`2` solubility model used to compute the amount of CO :sub:`2` dissolved in the brine phase as a function of pressure (in Pascal), temperature (in Kelvin), and salinity (in units of molality):

 The first keyword is an identifier for the model type (here, a flash model). It is followed by the model name. Then, the lower, upper, and step increment values for pressure and temperature ranges are specified.
 The trailing 0 defines a zero-salinity in the model.
