Rusal invests in sulphate production

Russia’s aluminium producer UC Rusal has commissioned a two-stage gas treatment centre at the Krasnoyarsk aluminium smelter (KRAZ) producing sodium sulphate. The investment amounted to USD1.14m. Developed by the Engineering and Technological Centre of Rusal the new process offers numerous advantages: there are no liquid and solid waste discharges thanks to a two-stage gas treatment consisting of wet and dry gas scrubbing. Sodium sulphate is generated at the first stage, which is used in production of cellulose, glass, detergents and construction materials. The advanced process will make it possible for Rusal to stop building new waste disposal areas at KRAZ and save up to USD1.39m per year. Also, gas scrubber maintenance costs will be reduced.
