Nornickel signed a contract with STEP to implement its sulphuric acid neutralisation project at Nadezhda Metallurgical Plant. This is the key milestone of the Sulphur Project, Nornickel’s most ambitious initiative to achieve major environmental improvements.
Part of the Fresh Air national project, the Sulphur Project relies on sulphur dioxide capture to produce sulphuric acid as well as gypsum following its subsequent neutralisation with natural limestone. As a result of the project, the sulphur dioxide recovery rate is set to reach at least 99% at the affected flash smelters, reducing emissions in Norilsk by at least 45% vs 2015.
“The sulphuric acid neutralisation initiative at Nadezhda Metallurgical Plant is a flagship part of the Sulphur Project. The project is on the way and we plan to finalise construction and installation as well as pre-commissioning by the end of 2022. This will result in a scalable production facility serving as a basis for the next stages of the Sulphur Project to be rolled out across all smelters in Norilsk,” said Sergey Dubovitsky, Vice President for Strategy and Strategic Project Management.
Under the contract, STEP will be constructing the main project facilities. With design documents approved by the state environmental review, the development of engineering documents is now underway. The Company has already signed contracts for the supply of main equipment components as well as for construction oversight and design supervision. The construction site is ready for the works to commence.
STEP is a general contractor with expertise in engineering management, procurement (including logistics management) and construction of highly sophisticated industrial facilities in diverse climatic environments. STEP has been working with the Norilsk Nickel Group on its major construction projects since 2014, including industrial facilities at Bystrinsky GOK and Kola MMC.
