Title (EN) METHOD FOR PRODUCING AMMONIA BY USING HIGH NITROGEN-CONTAINING NATURAL GAS
(FR) PROCÉDÉ DE PRODUCTION D’AMMONIAC FAISANT INTERVENIR DU GAZ NATUREL À HAUTE TENEUR EN AZOTE
(JA) 高窒素含有天然ガスを用いたアンモニアの製造方法
Abstract:
(EN) Provided is a novel method for producing ammonia by utilizing a high nitrogen-containing gas which was previously used only for combustion. In this method for producing ammonia, a natural gas (referred to as high nitrogen-containing natural gas) containing nitrogen at a high concentration of at least 4 vol% is used to obtain hydrogen, carbon monoxide, and carbon dioxide from hydrocarbon components in the natural gas by primary reforming with steam, the carbon monoxide and the steam are then converted to hydrogen and carbon dioxide by a shift reaction, and the resultant natural gas containing reduced amounts of carbon monoxide and carbon dioxide is used as an ammonia synthesis feed gas.
(FR) La présente invention concerne un nouveau procédé de production d’ammoniac faisant intervenir un gaz à haute teneur en azote qui a été précédemment utilisé uniquement pour la combustion. Dans ce procédé de production d’ammoniac, un gaz naturel (appelé gaz naturel à haute teneur en azote) contenant de l’azote à une haute concentration d’au moins 4 % en volume est utilisé pour obtenir de l’hydrogène, du monoxyde de carbone, et du dioxyde de carbone à partir de constituants hydrocarbonés dans le gaz naturel par reformage primaire au moyen de vapeur, le monoxyde de carbone et la vapeur sont ensuite convertis en hydrogène et dioxyde de carbone par une réaction de conversion, et le gaz naturel obtenu contenant des quantités réduites de monoxyde de carbone et de dioxyde de carbone est utilisé comme gaz de départ de la synthèse d’ammoniac.
(JA) 燃焼用以外に使用されていなかった高窒素含有天然ガスの新たな活用方法として、アンモニアの製造方法を提供する。 本発明のアンモニアの製造方法では、窒素濃度として4体積%以上の高濃度窒素を含有する天然ガス(高窒素含有天然ガスという)をスチームを用いる一次改質により天然ガス中の炭化水素成分から水素、一酸化炭素、二酸化炭素を得たのち、シフト反応で一酸化炭素とスチームを水素と二酸化炭素に変成した後に、一酸化炭素、および二酸化炭素を低減したものを、アンモニア合成原料ガスとして使用する。
