Abstract

To produce non-ferrous metals, the SO2 gas is also generated from the raw material such as sulfide or sulfate. A process that produces Elemental sulphur from non-ferrous smelter gas and waste plastics was investigated. <BR>Polyethylene was used as a deoxidizer of SO2 gas in the present study. The conditions for reaction of SO2 and polyethylene to make gas mixtures of H2S and SO2 were calculated thermodynamically. The Claus reaction was applied to produce elemental sulphur from H2S and SO2 gas mixture. More than 90% sulphur recovered from SO2 gas in small experimental furnaces used in the present study.
