Title
(DE) VERFAHREN ZUR ENTFERNUNG VON CO2 AUS ABGASEN
(EN) METHOD FOR REMOVING CO2 FROM EXHAUST GASES
(FR) PROCÉDÉ POUR L'EXTRACTION DU CO2 DE GAZ DE COMBUSTION
Abstract
(DE)
Gezeigt wird ein Verfahren zur Entfernung von CO2 aus Abgasen (4) von Anlagen zur Roheisenherstellung oder von Synthesegasanlagen, wobie die von CO2 gereinigten Abgasse anschliessend in einer Direktreduktionsanlage (33) eingeseitzt werden. Es ist dadurch gekennzeichnet, dass aus dem Abgas (4), das aus dem Verfahren der Roheisenherstellung oder der Synthesegasherstellung abgezogen wurde, vor dessen Verwendung in einer Direktreduktionsanlage (33) das CO2 mittels chemischer Absorption (1) entfernt wird, wobei die Wärme zur Regeneration des Absorptionsmittels zumindest teilweise aus spezifischen quellen.
(EN)
The invention relates to a method for removing CO2 from exhaust gases (4) of installations for producing pig iron or of synthesis gas plants, wherein the exhaust gases from which CO2 has been removed are subsequently used in a direct reduction facility (33). The method is characterised in that the CO2 is removed by means of chemical absorption (1) from the exhaust gas (4) drawn from the pig iron production process or the synthesis gas production process before the use of said exhaust gas in a direct reduction facility (33), wherein the heat for regenerating the absorption agent is obtained at last partially from specific sources.
(FR)
L'invention concerne un procédé pour l'extraction du CO2 de gaz de combustion (4) provenant d'installations d'élaboration de fonte brute ou d'installations d'élaboration de gaz de synthèse, les gaz d'échappement débarrassés du CO2 devant être finalement dirigés vers une installation à réduction directe (33). Ledit procédé est caractérisé en ce que le CO2 est extrait au moyen d'une absorption chimique (1) du gaz de combustion (4) qui s'échappe lors du procédé d'élaboration de fonte brute ou de gaz de synthèse, avant son utilisation dans une installation à réduction directe (33), la chaleur pour la régénération du moyen d'absorption étant fournie au moins en partie par des sources spécifiques.
