Abstract
La présente invention a pour objet un procédé d'obtention d'une charge gazeuse en vue d'une réaction chimique et de séparation d'un produit de réaction gazeux formé au cours de ladite réaction, dans lequel la charge gazeuse est obtenue par séparation en ses constituants d'un mélange gazeux brut renfermant ladite charge gazeuse, un gaz-vecteur ou mélange gazeux-vecteur, et dans lequel la partie de la charge gazeuse qui n'a pas réagi lors de ladite réaction chimique est recyclée vers la zone de réaction. Ce procédé est caractérisé en ce qu'il consiste à séparer en ses constituants le mélange gazeux brut et à isoler le produit de réaction gazeux dans une seule installation d'adsorption comportant des adsorbeurs à pression alternante à commutation cyclique. L'invention s'applique à la fabrication d'ozone, la synthèse de l'ammoniac et analogues.
