Is there a correlation to calculate the density of ethanol-water vapor mixture at high pressure and temperature? thank you!

You can calculate it using any EOS. For high pressure Peng-Robinson EOS gives the most accurate results.

Thank you! =)

Ethanol-Water mixtures properties should be evaluated using the fluid package UNIQUAC as recommended in HYSYS tutorials. NRTL property pacakge has also been used for ethanol-water mixtures. Peng-Robinson is not the right property package for Ethanol-Water mixtures.

Many times for my assignments I have been using PR EOS, even for ethanol - water mixture, to calculate properties and I always more or less accurate results.
