I am comparing phase diagrams generated by different models (Peng-Robinson, Soave, Lee Kesler Ploecker, GERG 2008 etc.) for mixtures with hydrocarbons + water,
I would like to use GERG 2008 as reference but it seems that this model doesn't work with light hydrocarbons + water fractions > 0.01...
I have water solubility measurements in vapor for methane-water, ethane-water, propane-water etc. for each measurement I know
Temperature Pressure Water content in vapor phase (Y)
282 K 10 Bar.a 0.0012
I wish to calculate the BIPs for different models (such as Peng Robinson, Soave...
In a gas pipeline project I have several wet gas compressors (80-90% gas)
for these compressors preliminary spec. give a 85% polytropic efficiency,
which is the standard procedure to model these compressors ?
I can model as adiabatic (assuming 85% efficiency) but I would prefer a more accurate...
