VLE data regression (from solubility measurements)
VLE data regression (from solubility measurements)
(OP)
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 Redlick Kowng etc.) and compare results (vapor-liquid equilibria),
my free copy of Prode Properties includes the procedure however I do not know how to enter X1 and Y1 (as I know only Y1),
is that possible with the free copy of Prode ?

RE: VLE data regression (from solubility measurements)
set water as first component, enter your Y values and set X values to 1
here below the two steps (I have included some points from water-methane tables)
by the way you can then simply solve a series of flash operations at specified T,P
to verify accuracy of different models,
see the procedure for SLE data regression discussed in operating manual

data regression in free version is limited to two components only
