Abstract

La présente invention concerne un procédé de rénovation d'une installation combinée d'un haut-fourneau alimenté en fluide oxydant issu au moins partiellement d'une unité de séparation des gaz de l'air (ASU). Selon ce procédé, plus de 50 % du débit de la soufflante qui alimente le haut-fourneau avant rénovation est injecté dans une unité cryogénique de séparation des gaz de l'air afin de produire de l'oxygène de pureté supérieure à 90 % 02 vol qui alimente le haut-fourneau, le débit d'air de la soufflante et/ou la pression de l'air issu de la soufflante étant contrôlés par un régulateur qui mesure ce débit et/ou cette pression à l'entrée et/ou à la sortie de l'étage d'épuration d'air, placé en amont de l'unité de séparation, de manière à contrôler le débit ou la pression de l'air issu de la soufflante, le fluide d'alimentation du haut~fourneau étant constitué par l'oxygène pur ou dilué avec de l'air produit par l'unité cryogénique de séparation.
