RUSAL’s Dry Gas Cleaning Systems Awarded For Eco-efficiency

Moscow, 23 December, 2020 – RUSAL (SEHK: 486; Moscow Exchange: RUAL), a leading global aluminium producer, is pleased to receive the Vernadsky National Environmental Award in the category "Innovative eco-efficient technologies in industry and energy".‬‬

In a bid to achieve this award, a joint team, of specialists from RUSAL’s scientific divisions; the SibVAMI (Irkutsk), RUSAL ITC (Krasnoyarsk), Bratsk (BrAZ), Novokuznetsk (NkAZ) and Irkutsk (IrkAZ) aluminium smelters, presented the company’s latest technological development – a "dry" gas cleaning system (DGCS) for waste gases in aluminum production. The new technology allows the Company to capture over 99.5 % of hydrogen fluoride and solid fluoride gases and provides significant savings in capital costs.

The project to retrofit RUSAL's smelters with its own DGCS has been implemented since 2017. Engineering solutions within the framework of this technology are patented. Eight DGCS’ developed and manufactured by RUSAL are already in operation at the Bratsk (BrAZ), Novokuznetsk (NkAZ) and Irkutsk (IrkAZ) aluminium smelters. More than 20 modern gas cleaning systems will have been installed at the Company’s sites by 2025. Overall, from 2017 to 2024, the amount of capital expenditure, allocated to the environmental retrofitting programme at the BrAZ, NkAZ and IrkAZ, including DGCS’ installation and the transition to Eco-Soderberg technology, totals more than 18 billion rubles.

"The overwhelming evidence of both DGCS’ energy efficiency and environmental friendliness along with its positive effect on CAPEX allowed RUSAL to switch swiftly to the use of its own technology and equipment, replacing foreign analogues. Support for and recognition from the expert community of corporate efforts to introduce new technological innovations is always important. It provides an additional incentive to continue long-term research aimed at improving environmental performance and encouraging the competitiveness of the Russian aluminum industry, and consequently, the entire national industry as a whole," said Viktor Mann, RUSAL’s Technical director.
