:: RUSAL Completes Modernization at Krasnoyarsk Aluminium Smelter
RUSAL announced that the completion of its 5 year environmental modernization program of the Krasnoyarsk aluminium smelter in Siberia. The company invested over USD 300 million in the program.
Earlier KrAZ commissioned a new gas treatment plant the 23rd in succession which marked the completion of the environmental modernization program launched in 2004. The aims of Clean Soederberg a modernization program developed by RUSAL’s Engineering and Technology Centre were to reduce environmental impact and improve efficiency of the smelting facility. As part of the program, KrAZ equipped its potrooms with automatic alumina feeding systems installed new gas treatment equipment, converted to dry anodes and raised amperage in its potrooms.
The program, a RUSAL proprietary solution helps Soederberg smelting facilities, built several decades ago, to improve their environmental performance to an acceptable level and stay environmentally competitive with prebaked anode smelters. For example, the modernization program resulted in a reduction of KrAZ’s emissions per tonne of aluminium output including a 1.5 fold reduction in HF, a 2.7 fold reduction in tar and a 2.5 fold reduction in benz pyrene.
Mr Victor Mann technology development director at RUSAL said that “We believe in the great potential of Soederberg pots which represent over 60% of global aluminium production. This Clean Soederberg project of unprecedented size and results has given a second life to KrAZ. Certain emissions are now almost three times lower than before the project was commenced. We see our biggest challenge as being to apply this experience at RUSAL's other Soederberg plants and to secure global leadership in the highest international environmental standards."
