This paper presents the development of a system model for a pre-combustion CO2 capture process as part of an integrated gasification combined cycle power plant. This process entails the modelling of highly non-ideal; two-phase multi-component mixtures which are currently not supported by available Modelica media libraries or interfaces.

Therefore; an interface prototype was developed and tested for the modelling and simulation of the CO2 capture process. Limitations concerning the modelling approach and improvements targeting the computational efficiency are discussed. Recommendations about the design of a library for the use of external property estimation code in Modelica conclude the treatment.
