Carbon capture and sequestration (CCS) technology is going to play an important role in the countermeasures for climate change. The design of the relevant processes requires accurate knowledge of primary and derivative properties of various pure components and mixtures over a wide range of temperatures and pressures. This paper focuses on the derivative properties of pure components related to CCS. An equation of state (EoS) with strong physical basis is suitable for such calculations. SAFT and PC-SAFT EoS are used to predict these properties, and their performance is evaluated against literature experimental data. The pressures and temperatures for the calculations are selected so as to cover an adequate range for the CCS process. EoS predictions are in good agreement with experimental data, with the exception of the critical region, where higher deviations are observed.
