Hyundai Steel in Dangjin, South Korea, has ordered a blast furnace gas injection study from Primetals Technologies, set to be conducted in two phases.
Phase 1 will assess the effects of injecting hydrogen-bearing gases into the furnace through the tuyeres, focusing on production stability, yield, and emission reduction. It will also evaluate the impact of Sequence Impulse Process (SIP) technology, which pulses high-pressure oxygen to each tuyere, enhancing gas utilization and improving coke permeability by combusting fine char build-up.
Phase 2 will examine the physical layout options at the plant for each technology, including necessary pipework and associated capital costs.
The study aims to determine the most environmentally efficient operation for Hyundai Steel’s three blast furnaces at the Dangjin plant. This initiative is part of Hyundai’s action plan for a long-term technology roadmap that supports its goal of carbon neutrality by 2050. By integrating alternative gas injection with traditional carbon fuels, Hyundai Steel seeks to reduce CO2 emissions, enhance environmental performance, and lower operating costs while maximizing furnace production.
Founded in 1953 as Korea’s first steelmaker, Hyundai Steel is a leading global steel producer with both blast furnace and electric arc furnace facilities. Its extensive product portfolio includes steel plates, sheets, structural steel, coils, and H-sections, serving sectors such as automotive, shipbuilding, offshore structures, railways, and construction.
