Mechel Chelyabinsk Plant Switches to Natural Gas in Rolling Mills
Mechel Group’s Chelyabinsk Metallurgical Plant has switched to the mixed use of natural and blast furnace gases in the production process of rolling shops
Mechel Group’s Chelyabinsk Metallurgical Plant has switched to the mixed use of natural and blast furnace gases in the production process of rolling shops and a shaped casting shop. Previously, for the production needs of these workshops of the plant, a mixture of blast furnace gas and coke oven gas was used. Now, instead of coke oven gas, natural gas is used - the cleanest type of fossil fuel. When it burns, a much smaller amount of harmful substances is formed compared to other types of fuel. As a result of the work, atmospheric emissions will be reduced by 2 thousand tons per year.
To switch to a new mixed fuel, Chelyabinsk Metallurgical Plant upgraded two gas mixing stations for mixing 20% of natural gas into the blast furnace, and connected special gas pipelines that deliver fuel to the mill's rolling shops. The new mixed fuel will reduce sulfur dioxide emissions into the air of Chelyabinsk from 8% to 2.5% of the total sulfur emissions from Chelyabinsk Metallurgical Plant per year.
One of the important results of the project was the complete cessation of the discharge of coke condensate into the industrial effluents of the plant, which is formed in the process of cooling gas fuel. Thus, Chelyabinsk Metallurgical Plant has fulfilled another clause of the environmental agreement to reduce the impact on water bodies, which Mechel entered into with the Governor of the Chelyabinsk Region, Alexey Teksler, in 2020.
The project was implemented within the framework of a four-sided environmental agreement between the company, the Ministry of Natural Resources of the Russian Federation, Rosprirodnadzor, and the government of the Chelyabinsk Region.
