Russian Federation aluminium titan U.C. Rusal said yesterday it has begun testing operations for a pilot program dedicated to producing industrial electrolytic cells with inert anodes. The pilot program’s new anodes are notable due to their improved design and industry-leading low carbon footprint.
Rusal says the new design produced by the pilot program will replace the inert anode electrolytic cell currently being tested by the firm. The new design will take its place as the logical next step in carbon-free aluminium cell technology.
The firm says its new anode technology includes several new features that it says will reduce the carbon footprint of aluminium production to as low as 2 metric tons of carbon dioxide per metric ton of primary aluminium produced. The new technology will also improve the purity of primary aluminium, says Rusal, and it will also have a positive impact on the cost per metric ton of primary aluminium production.
The new experimental pot cell will have a production capacity of around 1 metric ton per day at a rate of 140 thousand ampere current rate, notes Rusal.
“This technology will increase efficiency and significantly improve the carbon footprint of aluminum production,” noted Rusal’s technical director Victor Mann.
Rusal did not specify a timetable for full production or reveal at which of its locations the pilot project is being undertaken. This pilot program is but one of several projects the firm has undertaken to reduce its carbon footprint, alongside other innovations like certified low-carbon primary aluminium and various other new smelting technologies.
