“…Raynal and Royon-Lebeaud (2007) used the same VOF method for gas-liquid flow simulations on a small scale and the results are further used on a large scale in three-dimensional calculations with a geometry corresponding to a complete packed column. Ataki and Bart (2006) investigated the wetting in the structured packing elements of Rombopack using the same VOF method and used simulation results to develop correlations for the effective area and liquid hold-up. They also described the effect of liquid properties on wetting.…”

“…In recent years, the VOF CFD approach has been used more and more to investigate wetting, the effective area and liquid hold-up in structured packing (Ataki and Bart, 2006;Hoffmann et al, 2006;Shojaee et al, 2011;Haroun et al, 2014;Sebastia-Saez et al, 2013;Iso et al, 2013;Iso and Chen, 2011). Indeed, this method is adapted to simulate wetting phenomena since it is possible to specify a wall adhesion angle in conjunction with the surface tension model (Raynal et al, 2009).…”

-Computational Fluid Dynamics (CFD) is today commonly used in a wide variety of process industries and disciplines for the development of innovative technologies. The present article aims to show how CFD can be used as an effective analysis and design tool for the development and design of packed gas/liquid absorption columns. It is first shown how CFD can be used for the characterisation of packings. The different hydrodynamic and mass transfer design parameters are investigated and adapted CFD methods are suggested. Secondly, column distribution internal development is discussed to show how CFD simulations should be performed to improve the design of gas and liquid distributors. An example of the development of new distribution technologies for floating installation of a reactive absorption column is also presented.Résumé -Utilisation de la dynamique des fluides numérique pour le design des colonnes d'absorption à garnissages -La dynamique des fluides numérique (Computational Fluid Dynamics, CFD) est aujourd'hui couramment utilisée pour le développement de technologies innovantes dans de nombreux domaines et procédés industriels. Cet article a pour objectif de montrer comment la CFD peut être utilisée comme outil d'analyse et de dimensionnement pour le développement des colonnes d'absorption gaz-liquide à garnissages. En premier, il est présenté comment la CFD peut être utilisée pour caractériser les différents paramètres de dimensionnement d'un garnissage (hydrodynamique et transfert). Les méthodes CFD appropriées sont suggérées et discutées. En second, l'utilisation de la CFD pour le développement et l'optimisation des internes de distribution gaz-liquide est exposée. Un exemple de développement par CFD d'une nouvelle technologie de distribution pour une colonne d'absorption réactive sur une installation flottante offshore est présenté.

“…The purpose of the one-fluid formulation is to describe the physical parameters for both phases using only one equation valid in the entire computational domain (Scardovelli and Zaleski, 1999). Combined with appropriate turbulent modeling, this method has been used to simulate the gas/liquid flow on a liquid film scale within packings (Ataki and Bart, 2006;Raynal and Royon-Lebeaud, 2007;Haroun et al, 2012). From local information, such as the liquid film thickness and liquid holdup but also the liquid film velocity at the interface and the wetting quality, one can further determine mass transfer parameters for different types of packings used in process simulations such as the liquid-side mass transfer coefficient and the effective area, respectively.…”

Re´sume´-Re´duction du couˆt du captage de CO 2 : mise en oeuvre d'une strate´gie de simulations multi-e´chelle pour un proble`me multi-e´chelles -Le captage et le stockage de CO 2 est un moyen important en vue de la re´duction des e´missions de CO 2 (International Energy Agency, 2009). Les proce´de´s de captage en post-combustion utilisant des amines sont conside´re´s parmi les options pre´fe´re´es pour le CSC (Captage et Stockage du Carbone). Cependant, le couˆt du CO 2 e´vite´est tre`s important et doit eˆtre re´duit. Cet article a pour objectif de montrer que la combinaison de diffe´rents outils de simulations re´alise´es a`diffe´rentes e´chelles permet une analyse fine des couˆts du CO 2 et des parame`tres associe´s responsables de ces couˆts a`diffe´rentes e´chelles. Il est tout d'abord montre´, a`partir d'une analyse technico-e´conomique a`l'e´chelle globale du proce´de´, que les couˆts d'investissements repre´sentent pre`s de la moitie´du couˆt du CO 2 total. En se focalisant sur ce dernier couˆt, une analyse de sensibilite´base´e sur des simulations Aspen a`l'e´chelle interme´diaire de l'absorbeur, permet d'identifier les parame`tres cle´s re´gissant le transfert de matie`re et le dimensionnement de la colonne. On montre que le parame`tre le plus important est l'aire interfaciale, les coefficients de transfert de masse en phase gaz et en phase liquide n'ayant que tre`s peu d'influence. Enfin, des simulations CFD (Computational Fluid Dynamics) re´alise´es a`grande et petite e´chelles permettent d'orienter l'optimisation du design des colonnes via, d'une part, l'e´tude de l'interaction entre distributeurs et lit de garnissage, et d'autre part, la de´termination a`l'e´chelle locale de la perte de charge ou de parame`tres de transfert de masse. Une discussion porte sur l'utilisation couple´e de ces diffe´rents moyens de simulations qui permettront a`terme d'aller plus loin dans le de´veloppement de technologies et la re´duction des couˆts de captage du CO 2 .Abstract -CO 2 Capture Cost Reduction: Use of a Multiscale Simulations Strategy for a Multiscale Issue -Carbon Capture and Storage (CCS) is one important option for CO 2 mitigation (International Energy Agency, 2009). Post-combustion capture processes using amines are considered one of the preferred options for CCS. However, the cost of avoided CO 2 is very large and must be reduced. The present article aims to show that combining different simulation tools used on different scales makes possible a fine analysis of CO 2 capture costs and the associated parameters responsible for these costs on different scales. It is first shown, from a macro-scale techno-economic analysis, that investments represent about one half of the total CO 2 cost. Focusing on this cost, a sensitivity analysis, via Aspen calculations performed on a meso-column scale, enables one to identify key mass-transfer parameters that control absorption column design. It is shown that the most important mass-transfer parameter is the interfacial area, the gas and liquid mass transfer coeffi...
