Title (EN) PROCESS FOR PRODUCING A METHANE-RICH GAS
(FR) PROCÉDÉ DE FABRICATION D'UN GAZ RICHE EN MÉTHANE
Abstract:
(EN) A process for producing a methane-rich gas comprising the steps of: a) mixing a feed gas, comprising carbon monoxide and hydrogen, and a recycled methane-rich gas, comprising methane, to produce a gas mixture, comprising carbon monoxide, hydrogen and methane; b) reacting at least part of the carbon monoxide and hydrogen in the gas mixture in the presence of a methanation catalyst to produce a methane-rich product gas comprising methane, carbon dioxide and water; c) treating at least part of the methane-rich product gas to remove carbon dioxide to produce a methane-rich carbon dioxide-lean gas; and d) recycling at least part of the methane-rich carbon dioxide-lean gas to mixing step a) as recycled methane-rich gas.
(FR) L'invention porte sur un procédé de fabrication d'un gaz riche en méthane comprenant les étapes consistant à : a) mélanger un gaz d'alimentation, comprenant du monoxyde de carbone et de l'hydrogène, et un gaz riche en méthane recyclé, comprenant du méthane, pour produire un mélange gazeux, comprenant du monoxyde de carbone, de l'hydrogène et du méthane ; b) faire réagir au moins une partie du monoxyde de carbone et de l'hydrogène dans le mélange gazeux en présence d'un catalyseur de méthanation pour donner un produit gazeux riche en méthane comprenant du méthane, du dioxyde de carbone et de l'eau ; c) traiter au moins une partie du produit gazeux riche en méthane pour éliminer le dioxyde de carbone pour donner un gaz pauvre en dioxyde de carbone riche en méthane ; et d) recycler au moins une partie du gaz pauvre en dioxyde de carbone riche en méthane à l'étape de mélange a) en tant que gaz riche en méthane recyclé.
