Web27 apr. 2024 · In response, recognizing that a proactive approach could give them a competitive advantage, leading steel players are setting their own emissions reduction targets and formulating strategies for reaching them. Three main pathways exist for incumbent players to decarbonize steel production. (See Exhibit 1.) Direct-Reduced … WebThere are several options how hydrogen can be used in iron and steel production: Hydrogen can be used as an auxiliary reducing agent in the blast furnace plus basic oxygen converter route (BF-BOF route). Also, Hydrogen can be used as the only or combined reducing agent in a process known as direct reduction of iron or DRI (H2-DRI).
WebThe iron and steel industry is responsible for a portion of 7-10% of the global CO2 emissions, it has to reduce its CO2 ... (CASE 2) or completely (CASE 3) with hydrogen as reducing agent. For the production of the hydrogen, the installation of a 110 MW and 350 MW Polymer Electrolyte Membrane (PEM) electrolyser plant is considered. The ... Web18 feb. 2024 · In BF-BOF steelmaking, iron ore, coke (high-carbon coal purged of volatile compounds), and limestone are added to a blast furnace, where the iron ore reacts with carbon monoxide to produce high-carbon crude iron and CO₂.The iron is then transferred to a basic oxygen furnace, where oxygen combines with some of the carbon in the crude …
Web8 apr. 2024 · DRI production: an application with a high potential. Unlike in blast furnaces, DRI production consists of the simple reduction of the metal. This operation only requires the use of hot reducing gases, such as carbon monoxide, hydrogen, or a mixture of both.
