NLMK Lipetsk, an NLMK Group company has launched an anhydrous cooling system for blast furnace slag as part of its environmental upgrade programme. This will enable it to reduce hydrogen sulfide emissions in the corresponding area by 3.5x and keep the smell from this chemical compound to a minimum.

The implementation of the complex marks NLMK Lipetsk’s Blast Furnace Shop No. 1 (three blast furnaces) full transition to dry slag cooling technology. The complex was built in place of a slag dump that had been accumulating since the 1970s. Close to 6 million tonnes of various materials were processed and more than 300,000 tonnes of iron were fed back into steel production in the course of the project.
