“Zaporizhstal” II&SW, after a large-scale upgrading, put into operation a complex of new equipment — sinter machine No.1, high-tech gas-cleaning system with two powerful electrical precipitators, exhauster section and compressed air plant. The ecological effect is at the level of 10% dust and gas emission into atmosphere of total emissions quantity. The investment volume put in this project makes up UAH 240 million.
High ecological specifications of the new production complex are guaranteed with complete automation of all the processes and with the modern system of gas removal and gas cleaning. The system provides concentration of dust at the outlet of the unit for at most 50 mg/m3, the absorbers contribute to reduction of SО2 concentration (sulphur dioxide) in exhaust gases up to 400 mg/m3, which meets the requirements of European norms. The efficiency of the new object consists of dust emission reduction for 240 t/year (about 70%), sulphur dioxide (SO2) — for 206 t/year (about 30%).
“Putting sinter machine No.1 with new gas cleaning system into operation is a milestone event not only for the Works but also for the whole region. We really want to change the ecological situation in Zaporozhye for the better, and intentionally invest funds into modern ecological equipment”, — the General Director of “Zaporizhstal” II&SW Rostislav Shurma underlined.
The new gas cleaning system includes two absorbers, fume-laden and clean gas mains, control and monitoring system for determination of hazardous substances content in exhaust gases. The electrical precipitators of the gas-cleaning system carry out cleaning of sinter gas by dry method; it permits to return back to production process about 6 thousand tons per year of trapped iron-bearing production waste and simultaneously to reduce environmental dust emissions. The new gas-cleaning system of sinter machine No.1 at “Zaporizhstal” Works does not have any other analogues system in Ukraine.
Upgrading of sinter machine No.1 with installation of high-tech gas-cleaning equipment is one of the key measures included in the “Programme of environment protection, efficient use of nature resources and ensuring of the environmental safety of Zaporozhye” and into the trilateral agreement between JSC “Zaporizhstal”, the Ministry of Environment and Mineral Resources of Ukraine and Zaporozhye Regional Council.
The next step of the ecological upgrading of the Works would be construction of an analogue gas-cleaning system at sinter machine No.2, the investments would make up about UAH 80 million.
