Models involved
• ThermoSystem contains – CPA, – PC-SAFT, – SRK and PR
• CPA and PC-SAFT are associating models (H-bonds)

Model parameters
• SRK and PR are 3-parameter modelsa0 energy b co-volumec1 correlation (T-dependence on a0)
• Based on the critical properties (Tc,Pc,)

Conclusions on ThermoSystem
• Finally compliant with PRO/II (8.0.3).
• Only contains a PT flash algorithm.
• Comments to PRO/II– It is not possible to produce phase envelopes of CO-
packages (but the built-in ones)

Conclusion on Unit Operations
• Once the legacy code is provided, it is straightforward to produce a CO-version
• Unfortunately, the engineers at the power plants do not use CO-compliant PMEs.(They build on in-house simulators)
