Abstract
Procédé de synthèse d'ammoniac et nouveau produit ainsi obtenu. Dans ce procédé, un courant de purge provenant d'une boucle de synthèse d'ammoniac est traité pour réduire sa teneur en ammoniac jusqu'à moins d'environ 0,5 % en volume; le courant de purge est alors mis en contact, à une pression élevée, de préférence au moins sensiblement la pression de synthèse supérieure à la pression atmosphérique, avec la face d'alimentation d'une membrane de séparation (dispositif de traversée 54) qui présente une traversée sélective de l'hydrogène par comparaison avec la traversée de chacun des gaz constitués par le méthane et l'argon ; une différence de pression totale est maintenue sur la membrane pour fournir une force d'entraînement pour la traversée de l'hydrogène à travers la membrane; on obtient un gaz traversant riche en hydrogène sur la face de sortie du produit ayant traversé; le gaz traversant est combiné avec le gaz passant vers la zone de réaction de synthèse d'ammoniac pour la transformation en ammoniac La présente invention est particulièrement utile pour fournir un procédé de synthèse d'ammoniac en utilisant une membrane de séparation pour traiter le courant de purge.
