RUSAL Launches 16th Gas Cleaning Unit, Boosting Eco-Friendly Aluminium Production
Novokuznetsk, 17 December 2024 – RUSAL, one of the world’s largest aluminium producers, has commissioned into test operation its sixteenth “dry” gas cleaning unit, SGOU RUSAL. Developed in-house, the system outperforms imported alternatives with superior technical capabilities. It efficiently purifies exhaust gases to meet regulatory standards while recycling captured materials back into production as raw inputs. The construction of gas cleaning units across its aluminium smelters stands as one of RUSAL’s flagship environmental initiatives.
The SGOU RUSAL dry gas cleaning unit, with a capacity of up to 330,000 m³/h and featuring a modernized bag filter, has been commissioned into test operation at the Novokuznetsk Aluminium Smelter (NkAZ). Developed by the RUSAL Engineering Department as part of the company’s import substitution program, the technology and equipment efficiently clean exhaust gases from electrolysis production.
With a cleaning efficiency exceeding 99.5%, SGOU RUSAL is compatible with both EcoSoderberg electrolyzers and electrolyzers with baked anodes. Equipped with advanced automation systems, the units require less maintenance than foreign alternatives and demonstrate superior reliability in the extreme cold of Siberian winters.
“The construction of cutting-edge gas cleaning units is a key pillar of RUSAL's environmental initiatives. During the development of this technology, we secured two patents and introduced several innovative solutions. These advancements have enabled us to halve the construction footprint, reduce metal consumption, and optimize both the composition and quantity of equipment. As a result, we achieved greater efficiency and significantly lowered equipment costs compared to competing foreign alternatives,” said Vyacheslav Grigoriev, Deputy Technical Director and Head of the SGOU RUSAL Project.
The newly commissioned gas cleaning unit is the fourth installed at NkAZ and the 16th across RUSAL's aluminium smelters in Bratsk, Irkutsk, and Novokuznetsk. RUSAL plans to build a total of 24 such units, while its remaining smelters currently operate with foreign-made systems. By deploying its in-house solution, the company has achieved cost savings of approximately $10 million.
