A method of forming sulphur by the partial oxidation of hydrogen sulphide (H2S) wherein hydrogen sulphide (H2S) gas and an oxidant gas are supplied to the inner region of a flame while a gas comprising sulphur dioxide (SO2) is supplied to an outer region of the flame. The apparatus comprises burner 2 is operated so as to establish a flame in a furnace 72 to which the oxidant gas, typically oxygen, and hydrogen sulphide gas are supplied via passageway 8 to the inner region of the flame and sulphur dioxide is supplied via passageway 18 to the outer region of the flame. The sulphur dioxide may be supplied from a Wellman-Lord plant. The resultant gas mixture comprising sulphur vapour is withdrawn from the furnace 72, which may form part of a Claus plant. |
