PrJSC Dniprovsky Metallurgical Plant (DMZ, formerly Evraz-DMZ), a member of DCH Steel of the DCH group of businessman Oleksandr Yaroslavsky, has completed the first stage of overhaul of coke oven battery No. 4, which will reduce emissions of air pollutants.
According to the company’s press release on Thursday, the total investment is about UAH 170 million.
As part of the investment project, 20 coking chambers were repaired at the DMZ coke-chemical site. Repaired furnaces do not lose coke oven gas – all of it goes for treatment. Due to the sealing of the refractory masonry, the elimination of leaks into the heating system from the coking chambers and more complete combustion of gas in verticals, emissions of pollutants will decrease.
The press service also said that the excess of coke oven gas, which may be formed during the commissioning period, will be sent to the afterburner, the work of which is fully consistent with the technological process. The repair of the rest of the coking chambers will continue at the operating battery, and it is planned to complete it by the end of the year.
“DMZ is systematically engaged in the modernization of fixed assets at the coke-chemical site. In addition to the overhaul of coke oven battery No. 4, this year, ceramic surfacing is being carried out at coke oven battery No. 1 and coke oven battery No. 2 with sealing of heating walls. In general, this will increase the efficiency of the furnaces and significantly reduce the burden on the environment,” Director General of the DMZ Vitaliy Bash said.
At the same time, it is recalled that since 2016, DMZ has invested UAH 475 million in environmental programs. During this time, the company has reduced air emissions by almost 25%. Now the enterprise has an investment program in the amount of $400 million, aimed at modernizing production facilities and reducing the burden on the environment.
DMZ specializes in the production of steel, cast iron, rolled products and products from them.
