Resumen: From the presented experimental data of two CO2-rich mixtures containing SO2 and CO as impurities of anthropogenic CO2, we evaluated the impact of the simultaneous presence of these impurities on the transport, injection and storage of carbon capture and storage (CCS) technology. We determined the density, vapor-liquid equilibrium and speed of sound of a cocapture mixture (non-purified captured flue gas) [CO2 + 4.93 mol% SO2 + 3.01 mol% CO] and a mixture representative of European emissions (purified) [CO2 + 0.09 mol% SO2 + 1.12 mol% CO], measured from 263 to 373 K and pressures up to 30 MPa for the density and up to 190 MPa for the speed of sound. Using our experimental results, we validated two extended versions of the equation of state for combustion gases (EOS-CG) and the perturbed-chain statistical associating fluid theory (PC-SAFT) equation of state (EoS). From the calculation of selected operational CCS parameters, we concluded that, in the cocapture mixture, SO2 overcomes or compensates for the negative effect of CO, and then this mixture could be a favorable fluid for CCS. The negative effect of CO predominates in the emissions mixture. Differences in the chemical reactivity due to the studied impurities were not considered. © 2021 Institution of Chemical Engineers
