Korea Times reported that Hyundai Steel will reduce air pollutant emissions from its sinter plants by more than 50 percent by 2021 through operating a sinter gas treatment system. According to the company, the amount of pollutants emitted from sinter plants in Dangjin, South Chungcheong Province, has been reduced since it adopted an SGTS. The emissions of hazardous air pollutants, such as sulfur oxides and nitrogen oxides, have been reduced to the range of 30 ppm and 40 ppm from the original 140 ppm and 160 ppm.

The SGTS uses catalytic converters to remove nitrogen oxides and adds sodium hydrogen carbonate to the sinter mixture to remove sulfur oxides from waste gas.

Two of three SGTS started operations in May and June, respectively, and the additional system will be completed by June 2020.

If all three systems operate without a break, the company expects to reduce the amount of hazardous air pollutants to 10,000 tons in 2021 from 23,292 tons in 2018.
