Title (EN) A PROCESS FOR PURIFICATION OF A SYNTHESIS GAS CONTAINING HYDROGEN AND IMPURITIES
(FR) PROCÉDÉ DE PURIFICATION D'UN GAZ DE SYNTHÈSE CONTENANT DE L'HYDROGÈNE ET DES IMPURETÉS
Abstract:
(EN) A process for purification of a current of hydrogen synthesis gas (100), particularly in the front-end of an ammonia plant, wherein said gas contains hydrogen and minor amounts of carbon monoxide, carbon dioxide, water and impurities, said process including steps of methanation (13) of said current (100), converting residual amounts of carbon monoxide and carbon dioxide to methane and water, dehydration (14) of the gas to remove water, and then a cryogenic purification (15) such as liquid nitrogen wash, to remove methane and Argon; a corresponding plant and method for revamping an ammonia plant are also disclosed.
(FR) L'invention concerne un procédé de purification d'un flux de gaz de synthèse d'hydrogène (100), en particulier dans la première partie d'une installation de production d'ammoniac, ledit gaz contenant de l'hydrogène et de petites quantités de monoxyde de carbone, de dioxyde de carbone, d'eau et d'impuretés, ledit procédé incluant les étapes de méthanation (13) dudit flux (100), convertissant les quantités résiduelles de monoxyde de carbone et de dioxyde de carbone en méthane et eau, de déshydratation (14) du gaz afin d'éliminer l'eau, puis une purification cryogénique (15) comme un lavage à l'azote liquide pour éliminer le méthane et l'argon. L'invention concerne également une installation correspondante et un procédé de modernisation d'une installation de production d'ammoniac.
