摘要：A gas stream comprising hydrogen sulphide is preheated in a heat exchanger 2.Part of its hydrogen sulphide content is burnt in a furnace 6 to form sulphur dioxide and water vapour. Pure oxygen or oxygen-enriched air is used to support combustion. The sulphur dioxide reacts with residual hydrogen sulphide to form sulphur vapour and
further water vapour. The sulphur vapour is removed from the gas stream in a condenser 14. The gas stream is then divided into first and second subsidiary streams. The hydrogen sulphide content of the first subsidiary stream is totally converted to sulphur dioxide in an incinerator 16 using pure oxygen or oxygen-enriched air to support its combustion. Water vapour is then removed from the first subsidiary stream in a condenser 20, and the resulting gas stream now relatively rich in sulphur dioxide, is recycled to the furnace 6. The second subsidiary stream is subjected to a plurality of stages 26 of catalytic reaction between hydrogen sulphide and sulphur dioxide to form further sulphur vapour which is removed therefrom.
