Mixing supercritical condensate and water 1

[MortenA]

Anybody got a good reference for properties of a mixture of a light condensate (mostly propane and butane) and water at 220 barg (and higher pressure)?

Oh man. I'd think you could use corresponding states to get you in the ballpark until you find something better. That method might be off by 30% or more but it's a start.

which properties ?
for some transport properties (thermal conductivity, viscosity) there are methods such as Enskog theory of transport properties (starting from values calculated with a EOS)
but it depends from specific cases.

 

[MortenA]

apetri, yes viscosity, surface tension, density those kind of things

 

[apetri]

for density you may adopt some EOS, errors should be within a few %,
for viscosity, thermal conductivity etc. the Enskog theory of transport properties can help,
see for example

there are several other methods, just to mention a few,

Thanks for your reference. I will have a look at it - it looks promising!
