This paper presents the development of a system model for a pre-combustion CO 2 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 CO 2 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.
