Abstract (en)

[origin: FR2859483A1] The process, in which iron is smelted in a blast furnace (4) using fuel and an oxidant, comprises recovering the gases output by the furnace and separating the CO 2from them. The CO 2flow is purified so that it contains no more than 1 wt.% CO and not more than 500 ppm of sulfur, and is liquefied for transportation by pipeline, road or other means to an oil well site so it can be injected at a pressure of about 70 x 10 5>Pa to facilitate petroleum extraction. The purification can be carried out before or after liquefaction, and the other gases from the blast furnace can be used in a reheating furnace, heat exchanger or power generating plant.
