“…Among the numerous articles dealing with that subject, the paper by Krishna et al (1999a) can be considered as a pioneering work. The authors showed that, provided an appropriate drag law is selected for the interphase momentum exchange term, the Euler/Euler model is appropriate to determine the clear liquid height above the tray.…”

-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.

“…The essential difference between CFD and other technologies is that it is based on the physical analysis, rather than mathematical deduction, which is more close to reality. In the process of numerical simulation, CFD can deepen the understanding of the physical process, which is very useful in the analysis and interpretative in the results [5][6][7].In order to overcome the problem of trace distillation, where recombinant concentration is very low whereas the demand of separation remains is high, Li Suya [8] proposed a method by adding mesh on the ordinary sieve tray to achieve the separation effect, and this method was proved effectively by experiments. Based on Li's study, by using of large commercial CFD fluid simulation software FLUENT 6.3.26, this paper aims to find out the best configuration condition through analyzing the effect of the mesh layers, installation height, and opening rate on gas-liquid two-phase flow field [8].…”

A computational fluid dynamics model was developed to investigate the hydrodynamic characteristics of a novel orthogonal fixed-valve tray, which offers a larger effective contact perimeter under the same orifice area than its previously reported counterparts. The liquid-gas phases were simulated in the Eulerian framework, with the interphase momentum transfer source term based on the experimentally obtained liquid hold-up correlation. The simulation results were consistent with the experimental data. In addition, the gas hold-up profile of this new design was compared with its triangular cousin under the conditions of a typical run, showing that the former has a higher froth height, which indicated better interphase contact on the tray.
