Vapor-Mixtures (real-gas calculation for high pressures) and Enthalpie Calculations
I would like to calculate the entropy or enthalpies (steam, specific and inner energy) using the SRK [suave-redlich-kwong] equation, the Wilson approximation and (if necessary) the Antoine equation. and the Clausius-Clapeyron equation for a mixture of 0.199 mol/l nitrogen and 0.811 mol/l carbon dioxide. The critical mixture parameters (critical point) as well as the enthalpies (specific, internal and evaporation) at 50 bar pressure and 150 bar pressure and at a constant 288.15 K are to be calculated in order to then form the difference to find out how much energy , preferably in the wet steam area, can be stored.
I am a little bit stuck. Now I try to find out which A-factors to use when (SRK, Wilson, ...). Is the a-factor of wilson only useable for mixtures and only for liquids?
