Russian steel maker Magnitogorsk Iron and Steel Works on the eve of the Day of Metallurgist MM GD Mr Pavel Shilyaev briefed the Governor of the Chelyabinsk Region Mr Alexey Teksler with the implementation of several investment projects of Magnitka. One of them is the reconstruction of a complex of gas cleaning units for capturing fugitive (secondary) emissions from the converter department of the oxygen-converter shop. The BCC of PJSC MMK with an annual capacity of over 10 million tonnes of steel per year is one of the most powerful among similar shops in the world. It was commissioned in 1990. The main task of the project for the reconstruction of dust and gas collection units and gas exhaust ducts of converters No 1, 2, 3 and the overflow section of cast iron at KKTs is to reduce emissions of pollutants into the atmosphere and into the working space of the converter department of KKTs due to more efficient collection and cleaning of flue gases generated when pouring cast iron from a mixer into a ladle, pouring cast iron into a converter and blowing a melt. As part of the project, in February 2020, a contract was signed with Primetals Technologies Austria GmbH for the supply of basic engineering and equipment for the reconstruction of a complex of gas cleaning units of the converter department of the KKTs. The construction cost is 3.5 billion rubles. As a result of the reconstruction of dust and gas collection units, the efficiency of dust and gas cleaning will increase; it is planned to completely eliminate fugitive emissions from converters in all operating modes. Thus, the negative impact on the environment will be minimized. After the project implementation, gross dust emissions of the BCC will be reduced by at least 500 tons per year.

An equally important environmental project is being implemented in the electric arc furnace shop. By May 2022, a new gas cleaning unit for the electric arc furnace No. 1 with a capacity of 2400 thousand cubic meter per hour will be built here . As a result of the project, dust emissions will be reduced by 300 tons per year. Construction cost of 2.7 billion rubles. A real breakthrough for MMK's blast furnace production will be the construction of the blast furnace No 11 complex. The contract for the implementation of this investment project between PJSC Magnitogorsk Iron and Steel Works and Paul Wurth, a subsidiary of the SMS GmbH group of companies, entered into at the end of June. The project is designed for 3.5 years. The cost of building blast furnace No. 11 is 61.3 billion rubles. The working volume of the new blast furnace will be 3.8 thousand cubic meters, the capacity of 3.7 million tons of pig iron per year. The new blast furnace will be built using the world's best technology.

The use of advanced technologies, high equipment of the new blast furnace complex with environmental protection facilities, as well as the decommissioning of obsolete furnaces will allow MMK only within the framework of this project to reduce emissions of harmful substances into the atmosphere by 6.6 thousand tons per year and CO2 emissions by 1 million 123 thousand tons per year.
