Abstract

L'invention a pour objet une installation thermiquement intégrée pour la production d'ammoniac et d'urée dans laquelle la chaleur perdue contenue dans le gaz brut de synthèse de l'ammoniac sortant du convertisseur de CO à la vapeur basse température est introduite dans les appareils consommateurs de chaleur de l'installation de production d'urée lorsque celle-ci fonctionne dans des conditions stationnaires et, lorsque cette dernière est arrêtée ou fonctionne dans des conditions non stationnaires, le gaz brut de synthèse de l'ammoniac est introduit dans un appareil consommateur de chaleur différent Après quoi, quel que soit l'appareil consommateur de chaleur utilisé, le gaz brut de synthèse de l'ammoniac est introduit dans le dispositif d'élimination du CO2 de l'installation de production d'ammoniac.The subject of the invention is a thermally integrated installation for the production of ammonia and urea in which the waste heat contained in the raw ammonia synthesis gas leaving the CO to low-temperature steam converter is introduced into the appliances consuming heat from the urea production plant when the latter is operating under stationary conditions and, when the latter is shut down or operating under non-stationary conditions, the raw ammonia synthesis gas is introduced into a Different heat-consuming device After which, regardless of the heat-consuming device used, the raw ammonia synthesis gas is introduced into the CO2 removal device of the ammonia production plant.
