Zaporizhstal Metallurgical Plant of the Dutch mining and metallurgical company Metinvest B.V. (Metinvest) Rinat Akhmetov and Vadim Novinsky announced the implementation of memorandums on joint actions in the field of improving the environment, signed between the plant and the Zaporozhye Regional State Administration, as well as with the Zaporozhye City Council.
“Zaporizhstal is the first enterprise in the industrial sector of Zaporozhye to transfer data from online monitoring of emissions to the public on the official website of the plant. The data reflects the efficiency of the treatment equipment on all modernized and new industrial units. Monitoring data is updated according to the daily average indicators of the devices, ”the press service of the plant reported.
Zaporizhstal implements the system of environmental monitoring of emissions within the framework of a comprehensive program of environmental transformation of production - all modernized facilities of the enterprise are equipped with control sensors at emission sources. The online monitoring system allows you to control the efficiency of the gas cleaning equipment and ensure the reliability of its operation within the design parameters.
The enterprise's website displays the average daily performance of treatment systems for capturing the most perceptible pollutant in metallurgy - dust. The monitoring system displays the operation of the technological gas cleaning of all six sintering machines, as well as the aspirations of the foundry yards and the charge feed of blast furnaces No. 3 and 4.
The indication of the online monitoring system provides for notification of the normal operation of the treatment plant in relation to the current emission standards, exceeding the standards, or on the calibration /repair of the device of the online monitoring system or the production unit to which the treatment plant belongs. For example, in parallel with the shutdown of blast furnace No. 4 for major repairs lasting 19 days, starting from May 11, 2021, the operation of aspiration units also stopped. The monitoring system will inform about the lack of data on the operation of the aspiration of the foundry yard and charge feeding of the DP-4 during this period.
Since 2012, Zaporizhstal has invested more than UAH 15 billion in environmental modernization. In addition to equipping the sinter plant with new gas cleaning units, blast furnaces No. 2, 3, 4 were reconstructed with modern aspiration systems. An environmentally friendly hydrochloric acid pickling line was built, which made it possible to completely eliminate the discharge from cold rolling shop No. 1 into the Dnieper River and sulfuric acid vapors into the atmosphere.
