Among the efforts to reduce the global warming effects CCS technology is anticipated to play an important role. The realization of large scale CCS will require further development and substantial scale-up of the technology compared to the scales that are tested at present. For further developing, designing, and improving CCS processes, it is absolutely necessary to be able to describe and predict the behaviour of the working fluids involved in the CCS chain. This is usually done by use of equations of sta te (EOS). For EOS development very accurate experimental values of the density over the whole fluid region (gases and liquids) are needed.
This project will focus on measurements of phase equilibria (TPx), density and speed of sound for CO2 rich mixtures (75mol%
