Hyundai Steel has succeeded in securing a technology for cleaning and emitting harmful gases that occur during routine maintenance of a furnace.
Steel mills around the world have a common practice of opening a furnace’s vents as part of routine maintenance. As a result, he was accused of spitting out large amounts of dust and other pollutants.
For the first time in the world, Hyundai Steel has managed to revise the vent opening while blocking harmful gas emissions.
Different teams at Hyundai Steel’s Dangjin Steelworks have teamed up to find a solution to solve the pollutant emission problem without opening the vent:
The way they did this was to install an additional primary safety valve on a roundabout line that led to the air vent.
Hyundai Steel developed the technology in collaboration with Danieli Corus, a Danish engineering company.
The primary safety valve technology drastically reduces costs and pollutants using traditional cleaning equipment.
Hyundai Steel completed the registration of the technology as international and European patents in February before the first furnaces were equipped with the technology.
The teams dedicated themselves to ensuring safety by assessing and investigating 374 hazard cases with European specialist companies.
Hyundai Steel received approval and a license for the primary safety valve, recognized last July for a drastic 97 percent reduction in pollutant emissions.
Chungcheongnam-do and the Ministry of the Environment observed the operation of the primary safety valve several times.
POSCO, the country’s leading steelmaker, had already expressed its intention to take its cue from the primary safety valve technology that is likely to cause a sensation in the global steel industry.
In the meantime, Hyundai Steel plans to work with Korean and foreign steelmakers to make global efforts to solve environmental problems.
Kim Hee-won, a Hyundai Steel team leader, said he wanted to send his team members praise for the performance.
