Title (EN) METHOD FOR THE UPGRADING OF THE GAS MIXTURE FROM A DEAERATOR ASSOCIATED WITH THE PRODUCTION OF A SYNTHESIS GAS, AND PLANT FOR IMPLEMENTING SAME
(FR) PROCEDE DE VALORISATION DE L'EVENT D'UN DE-AERATEUR ASSOCIE A UNE PRODUCTION DE GAZ DE SYNTHESE ET INSTALLATION POUR SA MISE EN OEUVRE
Abstract:
(EN) The invention relates to the recycling of gas mixtures from the stripping columns of one or more water deaerators used for the production of steam, intended for use in a method for generating a H2/CO synthesis gas involving the steam reforming of methane (or other hydrocarbon feedstock such as naphtha, fuel oil, methanol, etc.) or autothermal reforming associated with the production of high-purity steam which can be exported. According to the invention, the gas mixture is recycled in the fumes from the synthesis-gas-generation unit in order for the impurities in the gas mixture to be broken down therein.
(FR) Dans un procédé de génération d'un gaz de synthèse H2/CO par reformage de méthane (ou autres charges d'hydrocarbures de type Naphta, fioul, méthanol...) à la vapeur, ou par reformage auto-thermique, associé à une production de vapeur de haute pureté de apte à l'exportation, l'invention concerne le recyclage d'évent(s) des colonnes de stripage du (des) dé-aérateurs d'eau utilisé(s) pour la production de la vapeur. Selon l'invention, l'évent est recyclé dans les fumées de l'unité de génération du gaz de synthèse pour y décomposer les impuretés présentes dans l'évent.
