Abstract

Cette invention concerne un procédé et un appareil pour séquestrer le dioxyde de carbone contenu dans un gaz usé et le réutiliser sous forme de gaz recyclé sans problèmes d'émissions, ledit procédé comprenant : à supposer une source gazeuse divisée en un gaz de procédé et un gaz usé : mélanger le gaz de procédé avec un hydrocarbure et charger le gaz ainsi obtenu dans un reformeur pour reformer le gaz d'alimentation et obtenir un gaz réducteur; et charger au moins une partie du gaz usé dans un épurateur de dioxyde de carbone pour éliminer au moins une partie du dioxyde de carbone du gaz usé et obtenir un gaz pauvre en dioxyde de carbone qui est mélangé avec le gaz réducteur. Eventuellement, le procédé comprend également le chargement d'au moins une partie du gaz usé dans l'épurateur de dioxyde de carbone pour éliminer au moins une partie du dioxyde de carbone du gaz usé et obtenir un gaz combustible après ajout d'un hydrocarbure qui est chargé dans le reformeur. Eventuellement, la source gazeuse et le gaz réducteur sont associés à un procédé de réduction directe pour convertir l'oxyde de fer en fer métallique dans un four à réduction qui utilise le gaz réducteur, éventuellement après modification, et produit la source gazeuse.
