The Use of Hydrogen in the Iron and Steel Industry Direct reduction is a process for reducing iron ore in the solid state. Consumes 500 Nm. By 2050 this technology family accounts for around 7% of steel production from iron ore. US20130047782A1 - Green process for the preparation of ... Iron ore is reduced with hydrogen while in a solid state, hence the name direct reduction, to produce direct reduced iron (DRI) called sponge iron. In this case, the reduction proceeds from hematite (Fe 2 O 3) to magnetite (Fe 3 O 4), and further to wüstite (FeO) and metallic iron (Fe). Iron Reduction Technologies HYBRIT is conducting trials on the direct reduction of iron ore pellets using hydrogen in our pilot plant in Luleå, Sweden. Computer-generated image of the hydrogen-fueled iron ore direct reduction plant. Reduction O Fe. Blue hydrogen can result in emission reductions similar to green hydrogen. This project seeks to research and develop the use of ammonia (NH3) as a reliable renewable reductant for direct raw iron making from selected Western Australian iron ores. 31 March 2019. “Brazil is expected to have one of the lowest costs for hydrogen production by 2030, according to research by BloombergNEF,” BNEF said. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. The goal in principle is to eliminate carbon dioxide emissions from the steelmaking process by using only fossil-free feedstock and fossil-free energy in all parts of the value chain. Source: Primetals. The time needed to achieve a reduction degree of 65, 85, or 95 pct is plotted as a function of the degree of oxidation and reduction temperature as a surface. Reducing gases are produced from natural gas (gas-based DRI) or coal (coal-based DRI) called syngas, a … Direct reduction of iron is the solid state reduction of iron oxide into iron. The sponge iron is then melted down with steel scrap and further processed to make steel. In H2-based reduction, the iron ore is reduced through a gas-solid reaction, similar to the DRI routes. Some selected and important publications are listed in Table 1 according to their main output. Hydrogen direct reduction is a relatively unexplored process. What is hydrogen-based reduction? However, longer-term reductions will require the adoption of new direct reduced iron (DRI) and smelting reduction technologies that facilitate the integration of low-carbon electricity (directly or through electrolytic hydrogen) and CCUS, as well as … produced by the MIDREX® process Iron ore is reduced to metallic iron in the MIDREX® Shaft Furnace by . Brazilian iron ore major Vale has hiked its premiums for blast furnace (BF) and direct-reduced (DR) iron ore pellet for the first quarter of 2022. Direct reduced iron “Direct reduced iron” (DRI) technology often uses methane gas to produce hydrogen and carbon monoxide, which are then used to turn iron ore into iron. This is not a new concept. Direct Reduced Iron (DRI) is the product of the direct reduction of iron ore in the solid state by carbon monoxide and hydrogen derived from natural gas or coal. The principle of hydrogen direct reduction is that pre-heated iron ore is converted into direct reduced iron (DRI) in a shaft reactor, with hydrogen … HYBRIT (Hydrogen Breakthrough Ironmaking Technology) was started by SSAB, LKAB and Vattenfall to develop a fossil-free value chain for iron and steel production using fossil-free electricity and hydrogen. The HYBRIT technology involves replacing the blast furnace process, which uses carbon and coke to remove the oxygen from iron ore, with a direct reduction process where we use It is also the case that many industrial processes require chemical feedstocks, such as iron ore direct reduction for primary steel production, Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore into 4 + H. 2 = 3FeO + H. 2. The reducing gas is a mixture majority of hydrogen (H2) and carbon monoxide (CO) which acts as reducing agent. The reduction of iron ore by H2 occurs in two or three stages. HYBRIT has been working to develop the world’s first fossil-free steel since 2016. The game-changing process uses hydrogen as a reducing agent instead of CO produced from fossil fuels, allowing the iron and steel industry to efficiently tackle the decarbonization challenge. Hydrogen generated in an electrolysis unit is pre-heated in a condenser before being supplied to the shaft where it … hydrogen reduction iron ore gas Prior art date 1961-05-31 Legal status (The legal status is an assumption and is not a legal conclusion. The solution of the direct reduction of iron ore with hydrogen has high potential: (i) the process has a high conversion efficiency (up to 98%) at low temperatures (500–600 °C) and both the use of H 2 and the significantly lower operating temperatures reduce the energy consumption and fossil-based CO 2 emissions by over 75%; (ii) H 2 can be generated by competitive and … Direct Reduced Iron (DRI) is the second most viable source of virgin iron used in steelmaking after pig iron or hot metal produced in blast furnaces. The plant has a direct reduction shaft, where the reduction takes place, and a number of electrolyzers for the production of hydrogen using fossil-free electricity. Metso Outotec’s Circored technology is the only process for iron ore reduction based on 100% hydrogen that has proven its functionality and performance in an industrial-scale demonstration plant. The direct reduced iron is discharged in either hot (HDRI) or cold (CDRI) condition or is hot briquetted into iron briquettes (HBI). The pilot plant, the first of its kind, was completed in 2020 and the first hydrogen reduced sponge iron was produced in May 2021. The process uses hydrogen as a reducing agent instead of CO produced from fossil fuels, allowing the iron and steel industry to efficiently tackle the decarbonization challenge. It settled its first-quarter BF pellet premium at $55 per tonne, an increase of $8 per tonne from the last settlement of $47 per tonne, sources told Fastmarkets. of CO. Consumes 500 Nm. billion tons of iron . This project seeks to research and develop the use of ammonia (NH3) as a reliable renewable reductant for direct raw iron making from selected Western Australian iron ores. Research on fixed/moving or fluidized ore reduction was separately in-cluded in the Table. Reduction with hydrogen, in the best case produced via renewable energies, is a future-minded alternative to commonly used fossil fuels. Direct reduction processes, which reduce iron ore to metallic iron without any liquid phase, especially have the possibility to use a high percentage of hydrogen in the reducing gas mixture. The heart of direct reduction is the shaft furnace, which is filled with iron ore. Natural gas-based shaft reactors are commonly used in North and It is currently used less commonly than pig iron or steel scrap.

We aim to achieve the separation of H 2 with a purity of more than 97% from the waste gas of the existing plant, using a process known as ‘pressure swing absorption’. The only differentiating factor is that the reducing agent is pure H2 instead of CO gas, syngas, or coke. Steel is strong, long-lasting and cost-efficient – making it perfect for everything from washing machines to cars, bridges and skyscrapers. Hydrogen direct reduction of iron ore (HDRI)-EAF based steel production is the most viable alternative to BF-BOF based steel production, as the production of hydrogen with intermittent renewable energy generators has an additional benefit of providing flexibility to the electricity grid [7]. Hydrogen Direct Reduction of Iron Ore. iron. Using g rey hydrogen from natural gas reformation can reduce emissions by 2.1%. Iron ore is pre-heated and fed into a reduction shaft, where it is converted to direct reduced iron (DRI) and further compacted to hot briquetted iron (HBI). Iron ore is an iron-oxygen compound, i.e. The best grades of iron ore are actually sourced from lower-grade in situ ore bodies,” Eames says. Blue hydrogen can result in emission reductions similar to green hydrogen. This is equivalent to one third of the … Furthermore, two blast furnaces are replaced by an electric furnace in Oxelösund. This process is known as Direct Reduced Ironmaking (DRI). Circored technology is flexible in its production setup. Note: CCUS is carbon capture and storage, DR-EAF is direct reduction of iron paired with an electric arc furnace. direct reduction of iron ores (in pellet or in lump form) by the use of reducing gases in a solid-gas moving bed reactor. According to the World Steel Association, steel is the most commonly used alloy in the world. Only process worldwide directly using iron ore concentrate fines from ore beneficiation with particle sizes of 100% smaller than 0.15 mm; Low CO2 footprint due to usage of H2 as reduction agent Primetals Technologies develops breakthrough technology for carbon-free, hydrogen-based direct reduction for iron ore fines. Reduction by CO Reduction by H. 2. It builds on fluidized-bed reduction technology, does not require any agglomeration (such as sintering or pelletizing), and uses on 100% hydrogen as a feedstock. Assuming that renewable hydrogen is used, significant quantities of renewable electricity are needed to 1) produce hydrogen needed for the direct reduction of iron ore and 2) power the electric arc furnace and other components in this steelmaking process. The iron used in the steelmaking process is currently chemically reduced from iron ore through the use of fossil resources – natural gas or coal. The Direct Reduction of Iron Ore with Hydrogen The steel industry represents about 7% of the world’s anthropogenic CO2 emissions due to the high use of fossil fuels. O. Natural gas (and in some cases coal) is used as a reducing agent to enable this process. Figure: Shaft furnace for the direct reduced iron process. Carbon monoxide and hydrogen are used to dissolve out the oxygen in the iron ores. Reduction with hydrogen, in the best case produced via renewable energies, is a future-minded alternative to commonly used fossil fuels. The hydrogen-based DRI route accounts for a further 22%, taking advantage of India’s access to low-cost solar PV electricity in particular. 3 /t. of H. 2 Auxiliary systems and materials handling equipment can be common to several modules.

Research Online is the open access institutional repository for the University of Wollongong. “In other words, sometimes the purest iron ore can be made from relatively low-grade ore bodies that then use processing to separate the higher-grade iron ore and generate higher-grade products. The solid product is also called "sponge iron". Traditionally, DRI is produced from the direct reduction of iron ore using natural gas, but emerging technology is enabling the production of DRI using hydrogen as well. the furnace with the top gas. DRI is produced by direct reduction of iron ore using carbon monoxide and hydrogen. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. furnace. Simplified comparison of the conventional direct reduced iron ore process (DRI) using natural gas versus a green hydrogen route which produces significantly less CO 2 emissions.. Unlike in traditional furnaces, steam rather than carbon dioxide is produced using this technology. 4. MIDREX direct reduction plant in Hamburg [4]. The second technology option is the direct reduction of solid iron ore pellets by hydrogen at temperatures above 570 °C [,,]. Direct reduction processes, which reduce iron ore to metallic iron without any liquid phase, especially have the possibility to use a high percentage of hydrogen in the reducing gas mixture.

Chemical Processes to Reduce Iron Oxide Fe. Hydrogen, as an energy carrier, has applications in other HYBRIT will moreover show the viability of technologies needed to melt hydrogen-reduced iron into crude steel. In 2021, a pilot plant in Sweden tested this process. In the EAF process, some scrap can also be added to reduce the need for iron ore. DR-EAF route with green hydrogen, either using a shaft furnace or a fluidized bed reactor, where hydrogen is the sole reducing agent [1]. Source: Roland Berger 2020. Reduction with hydrogen, in the best case produced via renewable energies, is a future-minded alternative to commonly used fossil fuels. Major initiatives underway worldwide to use hydrogen to make iron are described in the Appendix to this article. Operation with hydrogen as reductant enables reduction with very low CO 2 emission values, and allows the application of low reduction temperatures minimizing sticking tendencies. A DRI plant uses natural gas to reduce iron ore, resulting in a significant reduction in CO 2 emissions compared with coal-based blast furnace ironmaking. Cleveland-Cliffs, Lurgi and LTV Steel built a 400,000 ton/year Circored direct reduction plant in Trinidad that used hydrogen from a steam reformer as its reductant and energy source. A new route for making steel from iron ore based on the use of hydrogen to reduce iron oxides is presented, detailed and analyzed. ENERGIRON is the innovative HYL direct reduction technology jointly developed by Techint and Danieli, and whose name derives from the unique DRI product which distinguishes this technology from other available processes.
