Title (EN) SYSTEMS AND METHODS FOR IMPROVING NATURAL GAS USAGE IN STEAM METHANE REFORMERS
(FR) SYSTÈMES ET MÉTHODES POUR AMÉLIORER L'UTILISATION DE GAZ NATUREL DANS DES VAPOREFORMEURS DE MÉTHANE
Abstract:
(EN) An improved hydrogen generation system and method for using the same are provided. The system includes an HDS unit configured to desulfurize hydrocarbons, a pre-reformer configured to convert heavy hydrocarbons within the process gas stream to methane, a reformer configured to produce a syngas stream and a flue gas, a PSA unit configured to produce a product hydrogen stream and a PSA off-gas stream, and means for cooling the flue gas against a combustion air and the PSA off-gas stream to a temperature below the dew point of sulfuric acid.
(FR) L'invention concerne un système de génération d'hydrogène amélioré et une méthode d'utilisation de celui-ci. Le système comprend une unité d'HDS configurée pour désulfurer des hydrocarbures, un pré-reformeur configuré pour convertir des hydrocarbures lourds à l'intérieur du flux de gaz de traitement en méthane, un reformeur configuré pour produire un flux de gaz de synthèse et un gaz de combustion, une unité PSA configurée pour produire un flux d'hydrogène de produit et un flux de gaz de dégagement de PSA, et des moyens pour refroidir le gaz de combustion en un air de combustion et le flux de gaz de dégagement de PSA à une température inférieure au point de rosée de l'acide sulfurique.
