MMK modernizes by-product coke production

The Magnitogorsk Iron and Steel Works is a leader among the enterprises of the ferrous metallurgy of Russia. Within the framework of the program for long-term development and technical re-equipment of the coke-chemical production of PJSC MMK, it is planned to build a coke oven battery No. 12 with a production volume of gross dry coke - fuel for blast furnace production - up to 2.5 million tons per year. The implementation of the project will provide opportunities for the alternate reconstruction of worn-out and decommissioning of coke oven batteries that have fulfilled their standard life. In addition, the use of modern equipment in the technological processes of coking will reduce the impact on the environment.

The design documentation, which received a positive conclusion from the Glavgosexpertiza of Russia, provides for the construction of a complex of coke oven battery No. 12 in two stages. At the first, it is planned to build two blocks of a coke oven battery with two dry coke quenching units, one desulfurization and denitration unit. At the first stage, a coal preparation shop, a liquid ammonia warehouse, coke sorting facilities, an air compressor station, a fire pumping station and engineering facilities for coke oven battery No. 12 will also be built. Its capacity in autonomous operation will amount to 1.25 million tons of coke per year. At the second stage, two more blocks of a coke oven battery with technological units will be built. The increase in production during the commissioning of the second stage will amount to 1.25 million tons of coke per year.

“Coke oven battery No. 12 with a capacity of 2.5 million tons of dry coke per year will enable MMK to disable five morally and physically obsolete batteries, reduce gross emissions by 11,350 tons per year, benzopyrene and formaldehyde by 9-12 times. The cost of this largest project is about 60 billion rubles, - said Pavel Shilyaev, General Director of PJSC MMK. - Due to the restrictions associated with the coronavirus pandemic, we had to postpone the implementation of this project in 2020. But now we intend to accelerate the construction of a new coke oven battery, the launch of the first stage should take place in 2022. And by 2023, the rest of the units will be launched ”.
