The notebook computes phase envelopes for two binary mixtures containing ethane and benzene (20 % ethane and 80 % benzene; 70 % ethane and 30 % benzene). This binary system exhibits a peculiar behavior called retrograde condensation (e.g. We get condensation as we increase the temperature or decrease the pressure). We use the SRK equation of state to compute equilibrium constants. The critical points are indicated and were obtained from HYSYS 3.2. The computed phase envelopes are similar to what is obtained using HYSYS 3.2.
