“…More specifically, the CCS technological chain involves three major steps: separation of CO2 from a gaseous stream; compression and transport; and geological storage in an appropriate location. A large number of studies (Allam, 2003;Krishnamurthy et al, 2014;Yazdanfara et al, 2015;Leimbrink et al, 2015;Spigarelli and Kawatra, 2013) are dedicated to the design of the most efficient carbon dioxide separation process that still represents 60 to 80% of the cost of the overall CCS chain. For post combustion CO2 capture, several technologies have been proposed including absorption, adsorption, cryogenic distillation, and membrane separation (Allam, 2003).…”

The impact of humidity and flue gas impurities on PIM-1 membrane performance for post combustion capture, i.e. CO2 permeability and CO2/N2 selectivity, is investigated in this study. The presence of humidity in the feed stream induces a decrease in the permeability coefficients of both CO2 and N2, from 7010 Barrer (dry state) to 4135 Barrer (%RH=50%) and 360 Barrer (dry state) to 250 Barrer (%RH=50%) respectively. PIM-1 shows also a high water permeability (58800 Barrer) which increases with the relative humidity of the feed. The interaction with flue gas contaminants (NOx, SOx, Water) leads to a dramatic decrease of the membrane performance even after short exposure and FTIR analysis confirmed modifications of the chemical structure of PIM-1 caused by the acid environment. These results indicate that test with flue gases have to be considered for all novel materials proposed for carbon capture applications since the decrease in membrane permeability in presence of water and other impurities has to be taken into account during the design of the separation process.

“…In this context, CCS techniques have been extensively studied in recent years as a mitigation option for reducing anthropogenic CO 2 emissions into the atmosphere. Different technologies are currently available for CO 2 removal from flue gases, including chemical (De Guido et al, 2018) and physical absorption, adsorption (Gutierrez-Ortega et al, 2017), permeation through membranes (Leimbrink et al, 2015) L. Pellegrini et al and low-temperature or commonly referred to as "cryogenic" separation. Recently, a great attention has been devoted to cryogenic separation methods for application not only to natural gas purification (De Guido et al, 2015) and biogas upgrading (Pellegrini et al, 2017), but also to nitrogen rejection (De Guido et al, 2019) and CO 2 capture from flue gas.…”

Carbon dioxide capture and storage (CCS) is an important option for climate change mitigation and it has been extensively analysed in recent years to face the climate challenge.A portion of the emitted CO 2 comes from fossil fuel power plants. Several post-combustion technologies are available for separating CO 2 from the flue gases produced by the combustion of fossil fuels. In recent years, low-temperature/cryogenic technologies (e.g., CO 2 capture by anti-sublimation) have been investigated for this purpose, which rely on the fact that CO 2 can be separated out of flue gas by freezing it out. As a consequence, when dealing with the design of this type of processes, it is of paramount importance to be able to satisfactorily predict the thermodynamic phase behaviour of the system of interest, which involves equilibrium conditions also in the presence of solid CO 2 .The classical approach for phase equilibria calculations involving a solid phase is based on the equality of components' fugacities in the different phases and on the use of an expression for the fugacity of the freezing component in the solid phase that can be derived by relating it to its fugacity in the vapor phase following a proper thermodynamic cycle. This work compares the predictions for solid-vapor equilibria (SVE) conditions of a flue gas mixture that are obtained using such a classical approach with those obtained using the RGibbs calculation block available in Aspen Plus ® process simulator. The latter one enables SVE calculations by minimizing the Gibbs energy. The obtained results are useful for determining suitable operating conditions for the separation process, depending on the desired level of CO 2 recovery to be achieved.
