However, the absence of simulation software for predicting their performances and optimising their geometry inside a flowsheet is limiting the industrialisation of these units. Preliminary to the development of such a simulation tool, flow characteristics, internal and external mass transfers inherent to heterogeneous catalytic reactions, convective, conductive, diffusive and radiative heat transfers are analysed, allowing the definition of simplifying assumptions. The identified relevant phenomena are then modelled and constitute the physical base of ProSec Reaction, the new heat exchanger-reactor simulation software. This software is validated by comparing the predicted values to the Air Liquide steam reforming pilot plant results and to three-dimensional simulation results as well (CFD). The excellent consistency between numerical and experimental results demonstrates the accuracy and the predictive potential of the developed one-dimensional model. In the specific case of wall-coated plate-fin heat exchanger reactors, a discrete two-dimensional model is built and allows the representation of radial temperature gradients in the material, which are intrinsic to these specific heat exchangers. Finally, optimisation perspectives of the Air Liquide pilot plant heat exchanger reactor channel geometry are evaluated thanks to ProSec Reaction. They demonstrate the flexibility and the benefits of this new simulation tool<\/p>\n<table width=\"100%\" border=\"1\">\n<tr>\n<td><strong>Author<\/strong><\/td>\n<\/tr>\n<tr>\n<td>Jean-Patrick BARB\u00c9<\/td>\n<\/tr>\n<tr>\n<td><strong>Date of presentation<\/strong><\/td>\n<\/tr>\n<tr>\n<td>5 septembre 2018<\/td>\n<\/tr>\n<tr>\n<td><strong>Keywords<\/strong><\/td>\n<\/tr>\n<tr>\n<td>\u00e9changeur-r\u00e9acteur, r\u00e9acteur milli-structur\u00e9, \u00e9changeur-r\u00e9acteur \u00e0 plaques et canaux, \u00e9changeur-r\u00e9acteur \u00e0 plaques et ailettes, mod\u00e9lisation, transfert de chaleur, transfert de mati\u00e8re, r\u00e9action catalytique h\u00e9t\u00e9rog\u00e8ne, intensification<\/td>\n<\/tr>\n<\/table>\n\n&nbsp;<br \/>\n\n<div class=\"eds-animate edsanimate-sis-hidden\" data-eds-entry-animation=\"bounceIn\" data-eds-entry-delay=\"0\" data-eds-entry-duration=\"1\" data-eds-entry-timing=\"linear\" data-eds-exit-animation=\"\" data-eds-exit-delay=\"\" data-eds-exit-duration=\"\" data-eds-exit-timing=\"\" data-eds-repeat-count=\"1\" data-eds-keep=\"yes\" data-eds-animate-on=\"load\" data-eds-scroll-offset=\"\">\n\t\t<div class=\"box info\">\n\t\t\t<div class=\"box-inner-block\">\n\t\t\t\t<span class=\"fa tie-shortcode-boxicon\"><\/span>\n<p style=\"text-align: justify;\"><strong>&#x2666; The full version is only available for subscribers <a style=\"text-decoration: none;\" href=\"\/en\/offre-du-greth\/\"><span style=\"background-color: #3db2ea; color: #fff;\">\"ESSENTIEL\"<\/span><\/a> or <a style=\"text-decoration: none;\" href=\"\/en\/offre-du-greth\/\"><span style=\"background-color: #c6002c; color: #fff;\">\"PREMIUM\"<\/span><\/a> of GRETh!<\/strong><\/p>\n<p>&#x2666; If you are already a member \/ subscriber, you must identify yourself by <a href=\"\/wp-login.php\"><strong>clicking here<\/strong><\/a>.<br \/>\n&#x2666; If you are not a member, you can consult the offer proposed by GRETh by <a href=\"\/en\/offre-du-greth\/\"><strong>clicking here<\/strong><\/a> as well as the conditions of membership by <a href=\"\/en\/conditions-adhesion\/\"><strong>clicking here<\/strong><\/a>.\n\t\t\t<\/div>\n\t\t<\/div>\n\t<\/div>","protected":false},"excerpt":{"rendered":"<p>R\u00e9sum\u00e9 : Le contexte industriel est favorable aux \u00e9changeurs-r\u00e9acteurs catalytiques intensifi\u00e9s puisqu\u2019ils permettent une diminution des limitations aux transferts de mati\u00e8re et de chaleur compar\u00e9 aux r\u00e9acteurs conventionnels.
