ArcelorMittal Kryvyi Rih will build a new tube furnace and continue the reconstruction of sinter shop No. 2
ArcelorMittal Kryvyi Rih presented at public hearings environmental impact assessment reports for two investment projects - reconstruction of a complex of buildings and structures of sintering machines No. 1-3 of the second aglo shop and construction of a tube furnace in the benzene department capture coke production. Public hearings were held with the participation of representatives of public environmental organizations, interested residents of the city, as well as specialists from ArcelorMittal Kryvyi Rih. The hearing was conducted by Andrey Tishchenko, a representative of the Ministry of Ecology and Natural Resources of Ukraine.
The first project presented is a continuation of the reconstruction of the sinter shop No. 2, which produces fluxed sinter for blast furnaces. Earlier, in 2014–2015, the complex of sinter machine ? 6 was reconstructed to restore its design capacity - 850 thousand tons of sinter per year, as well as to achieve emission standards and improve personnel working conditions. In addition, since 2017, the reconstruction of sintering machines ?? 4 and 5.
A draft was prepared for the renewal of sintering machines No. 1–3, which is planned to be completed by 2021. It includes the replacement of sintering carts and incendiary horn, dust removal conveyors from under the collectors of sintering machines, gas ducts, reconstruction of linear coolers, installation of a new scraper conveyor. Plus, the wet gas cleaning system will be replaced by a more advanced - dry, using electrostatic filters, which will increase the efficiency of gas cleaning from dust to 98.75%. The upgrade will also help increase the sintering layer to 450 mm and reduce fuel consumption.
Second project - At the public hearings, the construction of a tubular furnace in the benzene department of the coke-chemical recovery plant was held. After construction and commissioning of a new tube furnace, the old one, which has been used since 1983, will be decommissioned. To do this, dismantle the pipeline section of coke oven gas due to its wear, replace the pumps and the pipeline section for supplying cold absorption oil. Also update the section of the hot oil pipeline in the area of ??distillation columns. Finally, they will directly install the new tubular furnace, complete with the necessary equipment, and bring in new pipelines.
After commissioning of the new furnace, emissions will decrease by 6.57 tons per year, by greenhouse gases - by almost 400 tons per year.
Both projects do not envisage a significant environmental impact both in the course of the work and in the further operation of the facilities; they comply with the requirements of the current environmental legislation. Authors of the prepared reports and representatives of various services of ArcelorMittal Kryvyi Rih answered the questions of residents and the public.
