Abstract

Dans la présente invention, les mesures d'efficacité énergétique au sein du processus de craquage de l'ammoniac vont au-delà de l'obtention d'une configuration d'exportation de vapeur nulle. Un schéma de processus comprenant toutes les mesures d'efficacité énergétique associées à une meilleure intégration de la chaleur est ciblé, où l'énergie externe de l'OSBL peut être utilisée pour réduire la consommation d'ammoniac. Cette énergie externe est de préférence moins chère que le NH3 alimentation, alors seulement une réduction de H2 Le TCO est attendu. Par intermittence, les énergies renouvelables sont disponibles en abondance et à des prix très bas (inférieurs à ceux du NH3 sur une base par MJ). L'approche décrite dans la présente invention consiste à intégrer l'électricité dans le craquage de l'ammoniac sans réduction de l'efficacité globale (NH3 PCS+ Electricité pour H spécifiques2 production).
