“…Heating and cooling water tanks are used to provide the adsorption bed, condenser and evaporator with water at the desired temperatures. During the desorption stage of the cycle, the adsorption bed is heated to the temperature (80 °C) while the condenser is kept at 25 °C [1,[4][5][6][7][8][9][10][11][12][13][14][15][16][17]. During the adsorption stage of the cycle, the adsorption bed is cooled down to 25 °C and the evaporator to 15 °C [14,10].…”

Abstract:The chief objective of this study is the proposal design and CFD simulation of a new compacted copper wire woven fin heat exchanger and silica gel adsorbent bed used as part of an adsorption refrigeration system. This type of heat exchanger design has a large surface area because of the wire woven fin design. It is estimated that this will help improve the coefficient of performance (COP) of the adsorption phase and increase the heat transfer in this system arrangement. To study the heat transfer between the fins and porous adsorbent reactor bed, two experiments were carried out and matched to computational fluid dynamics (CFD) results.

“…Both hydrodynamic and transport models are standardised ones, and can be developed easily. The model used for characterising the hydrodynamics, called a BrinkmanForchheimer model, is a modification of the laminar Navier-Stokes equations in order to take into account the friction between the liquid and the catalyst particles (Augier et al, 2008). These hydrodynamic equations are solved coupled with the transport equations of chemical species, which consider the radial dispersion of the components in the porous media (Peclet numbers are evaluated using the correlation of Guedes de Carvalho and Delgado, 2001).…”

-Computational Fluid Dynamics (CFD) is increasingly used in the oil and gas industry. The present article aims to show how CFD can be used at all steps of the development of a new process, with a focus on refining technologies. Those different steps consist first of setting up tools that will be used during the development phase, second of obtaining data in complement with experiments required for the process development, and finally, of troubleshooting actions or technology developments that will make the process even more efficient. A large number of applications corresponding to various flow configurations, single-phase or gas-liquid, gas-solid or even gas-liquid-solid, characterised by significantly different scales and requiring adapted simulation approaches, are discussed based on original results and a review of the literature. Perspectives are given in particular on the multi-scale approach and physical phenomena coupling.Résumé -La simulation numérique des écoulements appliquée au développement de procédés dans le monde de l'industrie du pétrole et du gaz -une revue -La simulation numérique des écoulements, ou Computational Fluid Dynamics (CFD), est un outil de plus en plus employé dans les secteurs pétrolier et gazier. Cet article permet d'illustrer comment l'outil numérique est utilisé lors des différents stades de développement d'un nouveau procédé, en particulier dans le monde du raffinage. Ces différentes phases correspondent tout d'abord à la mise au point des équipements qui seront utilisés pour le développement, puis au complément des essais lors de la phase de développement proprement dite et enfin à des actions support pour la résolution de problèmes opératoires ou l'amélioration de technologies qui permettront d'optimiser le procédé. De nombreuses applications correspondant à différents types d'écoulements, monophasique ou gaz-liquide, gazsolide et gaz-liquide-solide, caractérisées par des échelles de résolution différentes et requérant des approches de simulations adaptées sont discutées sur la base de résultats originaux et d'une revue de travaux déjà publiés. Des perspectives sont aussi données tant sur les aspects approche multi-échelles que sur le couplage de phénomènes.

SMB chromatography design using profile advancement factors, miniplant data, and rate‐based process simulation

et al. 2009

View full text Add to dashboard Cite

This article describes a systematic miniplant-based approach to rapid development of simulated moving bed (SMB) chromatography applications. The methodology involves analysis of single-column pulse tests to screen adsorbents and operating conditions and to determine initial values of profile advancement factors used to specify flow rates for an initial SMB miniplant experiment. A lumped-parameter linear driving force rate-based model is developed by fitting process data from a single miniplant run. The data are fit in a two-step procedure involving initial determination of effective adsorption isotherm constants as best-fit parameters with subsequent adjustment of calculated mass transfer coefficients to refine the data fit. The resulting simulation is used to guide further miniplant work and minimize experimental effort. The methodology is illustrated with miniplant data for a binary protein separation showing excellent agreement between model results and process data generated over a wide range of operating conditions.
