Metso Outotec is introducing the next generation of its CircoredTM process for the direct reduction of iron ore fines. 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. The flexible CircoredTM process produces highly metalized DRI or HBI that can directly be used as feed material in electric arc furnaces for carbon-free steelmaking.The CircoredTM process is based on the extensive fluidized bed knowledge and experience developed and applied by Metso Outotec over decades in hundreds of plants for different applications. The process applies a two-stage reactor configuration with a circulating fluidized bed followed by a bubbling fluidized bed downstream. The typical plant capacity is 1.25 million tonne per year per line. Two or more lines can be combined using joint facilities and utility areas. In stand-alone plants, the produced DRI is briquetted to HBI to enable further handling and safe transport. As a general rule, the CircoredTM process can handle feeds with a particle size of up to 2 mm. However, depending on the decrepitation behavior, particle sizes of up to 6 mm are possible. For processing ultrafine (< 50 µm) ores or process reverts like scrubber dust, Metso Outotec has patented a simple micro granulation process.CircoredTM process benefits1. No fossil fuels required for reduction of fines, 100% hydrogen based2. Energy-intensive and costly pelletizing step is eliminated3. HBI or DRI can be fed directly to an electric arc furnace, improving energy efficiency4. Proven performance in industrial-scale demonstration plant using established fluidized bed processIf a CircoredTM plant is integrated into an existing steelmaking facility, energy efficiency can be further increased by direct hot feeding of the DRI to an electric arc furnace.CircoredTM is part of Metso Outotec’s Planet Positive portfolio.
