SUMMARY:HYFOR - Hydrogen-based fine-ore reduction: From an idea to a pilot plant
DESCRIPTION:The idea of the HYFOR-process was born in 2016, as a new disruptive fluidized bed technology using directly fine-ore as solid feedstock and green or low-carbon hydrogen as reducing agent. With this concept the issue of sufficient gas permeability is not prevailing, as it is for conventional shaft-based direct reduction technologies and the blast furnace. Therefore, an agglomeration step, e.g., sintering or pelletizing, is not necessary before charging the input materials and thus costs (Capex and Opex) and CO2-emissions can be reduced. As an accompanying benefit of using ore fines, the highest iron yield due to dry dedusting and recycling of dust can be achieved. The use of green or low-carbon hydrogen as reducing agent assures the avoidance or significant reduction of CO2-emissions during the reduction step. As the only technology, iron ore concentrates (pellet feed) as main iron source with particle sizes of 100% <150 µm, without prior agglomeration of any type of iron ore (e.g., hematite, limonite, magnetite) from high quality to low quality can be processed. First tests in the year of 2016 at the reduction lab of the Chair of Ferrous Metallurgy at the Montanuniversitaet Leoben showed the proof-of-principle of the HYFOR-technology. After promising results of all the lab-scale test work, the design and engineering of the HYFOR pilot plant started by the end of 2018. After erection and commissioning in 2021, roughly 30 test campaigns were done including several modifications and improvements. The main objectives of the pilot plant are to verify the results obtained during the lab-scale investigations, to evaluate the performance of the mechanical equipment, and to provide basic data for the design for a future industrial application.
