“…The normalized interfacial areas measured on the I-Ring#50 are in good agreement with those obtained by Linek et al (2001) with RSMR 50. However, they are higher than those obtained by Nakov et al (2007) with RSR 1.5. This difference can be explained by the use of different kinetic and different thermodynamic models.…”

“…(2009) have pointed out that the use of the chemical system 1N could lead to 10% lower interfacial area than the use of 0.1N. Moreover, Nakov et al (2007) used different kinetic and thermodynamic models. These differences could explain the trend observed on the IMTP50 ratios.…”

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.

“…The determination of the height is made using Aspen calculations with IFPEN in-house correlations for mass transfer parameters. Mass transfer correlations are based on either IFPEN internal data or literature data (Alix and Raynal, 2009;Nakov et al, 2007;Billet, 1995). All the calculations are carried out for a constant CO 2 capture rate of 90%.…”

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...

Absorption, or gas absorption, is a unit operation used in the chemical industry to separate gases by washing or scrubbing a gas mixture with a suitable liquid. One or more of the gas components dissolves or is absorbed in the liquid and is thus removed from the mixture. Absorption is currently one of the most important processes in chemical engineering not only for product recovery but also, and perhaps mainly, for pollutant removal. Intense industrial and academic effort is focused on optimizing the process, in terms process efficiency as well as commercial aspects. In this article, the fundamental principles of gas solubility and mass transfer, design and operation of industrial equipment with relevant examples of typical commercial gas absorption processes are discussed, including recent developments in these areas.
