Re´sume´-Pertes de charge, capacite´et aires de transfert de matie`re requises pour le captage du CO 2 en post-combustion par solvants -Les proce´de´s de captage en post-combustion utilisant des amines sont conside´re´s comme l'une des options pre´fe´re´es pour le captage et le stockage du CO 2 (CSC, CO 2 Capture and Storage). Cependant, le couˆt du CO 2 e´vite´est tre`s important et doit eˆtre re´duit. Ce couˆt est fortement lie´aux designs des colonnes, qui doivent, par conse´quent, eˆtre optimise´es. Dans cet article, les performances hydrodynamiques et le transfert de matie`re de garnissages vrac et structure´s sont discute´s en terme de perte de charge, de capacite´et, le plus important, en terme de coefficients de transfert de matie`re, notamment l'aire interfaciale, parame`tre le plus important pour la conception d'absorbeurs de CO 2 . La comparaison de diffe´rents garnissages commerciaux a`haute efficacite´est discute´e a`partir de caracte´risations expe´rimentales et de simulations CFD et une me´thodologie pour de futurs de´veloppements est propose´e.Abstract -Pressure Drop, Capacity and Mass Transfer Area Requirements for Post-Combustion Carbon Capture by Solvents -Post-combustion capture processes using amines are considered as one of the preferred options for CO 2 Capture and Storage (CCS). However, the cost of avoided CO 2 is very large and must be reduced. The latter cost is strongly linked with column designs which consequently must be optimized. In the present article, hydrodynamics and mass transfer performances of random and structured packings are discussed in terms of pressure drop, capacity and most importantly in terms of mass transfer parameters, in particular in terms of interfacial area which is the most important parameter for CO 2 absorbers design. Comparison of different commercial high efficiency packings is discussed from experimental characterization and from CFD simulations and a methodology for future developments is proposed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
