ArcelorMittal Kryvyi Rih will start construction of a tube furnace

ArcelorMittal Kryvyi Rih presented at public hearings reports on environmental impact assessment for two investment projects - reconstruction of the complex of buildings and structures of sintering machines No. 1–3 of the second sinter plant and construction of a tube furnace in the benzene section of the coke-chemical production plant.

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 hearings were moderated by Andrey Tishchenko, representative of the Ministry of Ecology and Natural Resources of Ukraine.

The first project presented is a continuation of the reconstruction of the sinter plant No. 2, which produces fluxed sinter for blast furnace shops.

Earlier, in 2014–2015, the complex of sinter machine No. 6 was reconstructed to restore its design capacity - 850 thousand tons of sinter per year, as well as to achieve emission standards and improve the working conditions of personnel. In addition, since 2017, the reconstruction of sinter machines No. 4 and 5 has been underway.

A project has also been prepared for the renewal of sintering machines No. 1–3, which is planned to be completed by 2021. It includes the replacement of sintering trolleys and an incendiary hearth, conveyors for removing dust from under the collectors of sintering machines, gas ducts, reconstruction of linear coolers, and installation of a new scraper conveyor. Plus, the wet gas cleaning system will be replaced with a more advanced dry gas cleaning system using electrostatic filters, which will increase the efficiency of gas cleaning from dust up to 98.75%. The retrofit will also help increase the sintering layer to 450 mm and reduce fuel consumption.

The second project at public hearings concerned the construction of a tube furnace in the benzene section of the by-product recovery department. After the construction and commissioning of a new tube furnace, the old one, which has been in use since 1983, will be decommissioned. For this, the section of the coke oven gas pipeline is dismantled due to its wear, the pumps and the section of the pipeline for supplying cold absorption oil will be replaced. The section of the hot oil pipeline in the area of ​​the distillation columns will also be renewed. Finally, the installation of a new tube furnace complete with the necessary equipment will be carried out directly, new pipelines will be installed.

After the commissioning of the new furnace, the volume of emissions will decrease by 6.57 tons per year, for greenhouse gases - by almost 400 tons per year.

Both projects do not provide for a significant impact on the environment both in the course of work and in the further operation of facilities, they comply with the requirements of the current environmental legislation. Answering questions from residents and the public,
