Hyundai Steel has succeeded in securing a technology to purify and emit harmful gases occurring during the routine maintenance of a furnace.

Steelworks around the world have a customary practice of opening the bleeders of a furnace in its routine maintenance, so it has been blamed for spewing large amounts of dust and other pollutants.

Hyundai Steel has managed to overhaul how it opens the bleeder while blocking harmful gas emissions, for the first time in the world.

Diverse teams from Hyundai Steel’s Dangjin Steelworks joined forces to find a solution to fix the problem of emitting pollutants without opening the bleeder:

The way they did that was to install an additional primary safety valve to a roundabout pipeline leading to the bleeder.

Hyundai Steel developed the technology in cooperation with Danieli Corus, a Danish engineering company.

The primary safety valve technology dramatically reducing costs and pollutants using the conventional purification facilities.

Hyundai Steel finished the registration of the technology as international and European patents in February before the first furnaces were outfitted with the technology.

The teams devoted themselves to securing safety by evaluating and scrutinizing 374 danger cases with European specialization firms.

Hyundai Steel obtained permission and a license for the primary safety valve, recognized for dramatically reducing pollutant emissions by 97 percent last July.

Chungcheongnam-do and the Ministry of Environment observed the operation of the primary safety valve on several occasions.

POSCO, the nation’s leading steelmaker, had already expressed its intent to take its cue from the technology involving the primary safety valve, which is expected to make a splash in the global steel industry.

Meanwhile, Hyundai Steel plans to join forces in making global efforts with Korean and foreign steelmakers to solve environmental problems.

Kim Hee-won, a team head of Hyundai Steel, said he wished to send praise for the accomplishment to his team members.
