VLE/LLE data regression in Properties

[stawad]

I am doing VLE / LLE (vapor-liquid and liquid-liquid) data regression in P RODE PROPERTIES,
input values are from Dortmund Data Bank,
PRODE requires to specify X1, Y1, Temperature and Pressure,
so for isothermal data sets I have the same pressure,
the first column allows to specify VLE or LLE points,
my question is, can I mix VLE and LLE equilibrium points ?
The procedure finds a solution but I am not sure which is the range of application for these calculated BIPs

[carlo.stenali]

that is possible,
generally you can obtain some "average" values for BIPs
which may produce a better fitting in processes where both
VLE vapor-liquid-equilibria and LLE liquid-liquid-equilibria
are present.
By the way,
once you have the BIPs
you can calculate a TPXY
or similar diagram to
verify the range of application for that binary.

stawad,
I follow the same procedure,
results (VLE fitting) are good.

make sure to select reliable VLE (or LLE) data,
(some data sets are predicted not measured)

[cmarc]

as confirmed by others you can mix
VLE / LLE points in data regression utility,
PRODE PROPERTIES allows to specify
VLE vapor / liquid
LLE liquid / liquid
SLE solid / liquid
equilibrium points
