Abstract

For more efficient, robust and inexpensive CCS systems, improvements of the models describing the behavior of fluids involved in CCS are required. Accurate models in turn require experimental data of high quality, which are still lacking for many important properties when impurities are present. SINTEF Energy Research and the Norwegian CCS Research Centre (NCCS) are addressing the lack of phase equilibrium data in CCS by performing accurate measurements of important systems using a purpose-built setup. So far, the binary mixtures of CO2 + N2, CO2 + O2, CO2 + CH4, CO2 + Ar, and CO2 + CO have been investigated. In the present paper, some examples from the measurements on CO2 + Ar and CO2 + CO systems are provided, illustrating that trusting models could lead to serious consequences if they are not supported by independently verified data.
