This paper presents the development and commercialization of a novel dust extraction technology. Driven by stringent EU emission regulations, the need for more efficient dust removal solutions has become paramount in industries like mining and metallurgy. By combining fundamental fluid dynamics research with industrial practice, SSAB researchers and Oulu University developed a modular dust...
Steelmaking in Europe is in transition, stepping away from the traditional blast furnace route towards electric arc furnace steelmaking. This conversion is driven by available green Hydrogen as well as by affordable electrical energy which will both become prerequisite.
Swiss Steel Group employs EAF technology in all of its 5 steel plants, enjoying a low CO2 footprint already today. As an...
Sekisui Chemical has been developing technologies to efficiently convert CO2 to CO with Reverse Water Gas Shift (RWGS) reaction by Chemical Looping(CL).
Among the various CO2 utilization approaches, RWGS reaction plays a pivotal role since it produces synthesis gas (CO + H2), the building block of numerous conversion processes. However, average CO generation yields are ~40-50% with...
The steel industry is a cornerstone of the European economy, contributing 6.7% of global crude steel production (126.3 Mt in 2023). However, it is also a major source of greenhouse gas emissions, accounting for 4% of total EU emissions and 23% of those from manufacturing industries. Achieving carbon neutrality in this high-energy-intensity sector requires innovative solutions to reduce...
The increasing need for steel has rised the consumption of metcoke where in Europe 45 million tons of metcoke are used annually in steelmaking processes. In the attempt for green transition, this growing need is accelerating the search for sustainable alternatives to fossil carbon products.
Pyrolysis of wood pellets from pine and spruce at temperatures above 500°C has proven effective in...
Desulphurisation in the steel ladle requires a reactive slag with high CaO dissolution. Conventional slag fluxing agents applied during this secondary metallurgical refining step include calcium aluminate additives and fluorspar to maximise the dissolved CaO. However, calcium aluminate additives can have a high carbon footprint due to their energy-intensive production process and the use of...
It is well known that global CO2 emission from steel sector is 7-8%, which is approx. 1/3 of industrial energy use. Hence, many steel companies are trying to develop the electric arc furnace (EAF) and/or electric smelting furnace (ESF) steelmaking processes instead of blast furnace (BF) and basic oxygen furnace (BOF) integrated routes by employing high amounts of direct-reduced iron (DRI)...
