BrineGas_3Gas is a medium package that, based on Brine.PartialBrineGas, defines a brine with 3 gases (CO2, N2, CH4), which are the main gases in the geofluid in Gross Schoenebeck, Germany.
It is based on Modelica.Media, the usage is accordingly:
Create an instance of the Medium (optionally deactivating range checks, for all options see .PartialFlags):
package Medium = BrineGas_3Gas(ignoreLimitN2_T=false);
Create an instance of Medium.Baseproperties:
Medium.BaseProperties props;
Use the BaseProperties model to define the actual brine composition(Xi or X), to define the thermodynamic state and calculate the corresponding properties.
props.p = 1e5;
props.T = 300;
props.Xi = {1-4, 7e-4, 6e-005} "CO2, N2, CH4"
d = props.d;
See BrineProp.Examples.BrineGas
for more usage examples.
Returns properties for given composition when _pTX functions are called directly. Returns properties for given gas composition + saturated water when called via state functions (e.g. density)
All calculated values are returned in SI units and are mass based.
Calculate water saturated composition externally once (instead of separately in each property function) and pass on.
