| Abstract: | Autogenous copper and nickel smelting processes give rise to oil-gases containing 20% or more sulphur dioxide, from which it is practicable to produce elemental sulphur. Technology for producting sulphur from these waste gases based on the reduction of the sulphur dioxide by natural gas is already in use on industrial scale at the Norilsk combine,. This technology can be improved to have even higher efficiency by using a catalyst at the stage of sulphur dioxide reduction. |
