Zaporizhkoks completes overhaul of regenerator for stable operation of the shop

Equipment modernization will improve coke oven gas purification and safety

Metinvest Group’s Zaporizhkoks , one of the largest producers of coke for metallurgy in Ukraine, has successfully completed the overhaul of regenerator No. 11 in the desulphurization shop. The company allocated UAH 3.9 million to upgrade the equipment, which will improve energy efficiency, ensure stable operation of the shop and increase industrial safety, the company said in a statement.

As part of the overhaul, the metal structures of the regenerator base were restored, new belt segments, body reinforcement and stiffening elements were installed. The metal structures of the roof with a fence and protective lining were also replaced, and the mortar pipeline and air duct were updated.

The regenerator plays a key role in the process of cleaning coke oven gas from hydrogen sulfide. High-quality purification ensures efficient operation of coke oven batteries and boilers at the thermal power plant, which is important for the stability of the entire production process.

The work performed will not only improve the environmental situation but also make production safer for employees.

In 2024, the company increased its coke production by 2.1% compared to 2023, to 874.6 thousand tons.

Since 2022, the company has allocated over UAH 360 million for the capital upgrade of the coke shop’s furnace stock. Most of the funds were invested in the overhaul of coke oven batteries No. 2 and No. 5-6. The latest investment projects include the overhaul of coke ejector No. 3 at coke oven battery (COB) No. 5-6 and the overhaul of the U-30 charge feeding line in the coal preparation shop.

Zaporizhkoks is one of the largest coke and chemical producers in Ukraine. It is a part of Metinvest Group. The main consumer of its products is Zaporizhstal Iron and Steel Works.
