Hello,
How can I get the partial pressure of a gas in a real gas mixture in HYSYS? is there a quick way other than going through the Z factor part?
Thanks,

No matter if the gas is real or imaginary the partial pressure is simply the total pressure X mol fraction component (Ptotal*yi). Presuming you know both.

perhaps partial pressure of a gas may be ambiguous,
you may wish to define the specific application,
for example, for phase equilibria you may need the fugacity,
then, for vapor+liquid fg(i)*Y(i) = fl(i)*X(i)
and equivalent expressions for additional phases,
some simulators export these values,
(I have Prode Properties which exports fugacities plus derivatives vs. W, T, P)
