The WP4 on Understanding the physical properties of CO2 to support CCUS industrial infrastructure has finalised a survey on establishing a protocol for the preparation of two types of binary mixtures composed of CO2+monoethanolamine and CO2+diethanolamine.
The report provides currently unavailable experimental measurements of the thermophysical properties of CO2 mixtures which will be needed to implement the empirical models developed in Task 4.2. UVa and INRIM will measure the density and the speed of sound respectively of CO2 + monoethanolamine between 30 °C and 140 °C and for pressures up to 12 MPa at the 3 different concentrations. The accuracy of the sample preparation will be determined in a comparison of the density measurements obtained by the two institutes at (40 and 120) °C at ambient pressure.
