Abstract:
Process for partial oxidation in a Claus furnace of at least one gas stream comprising hydrogen sulphide, comprising the steps of:(a) injecting at least one gas stream comprising hydrogen sulphide and at least one oxygen-enriched gas stream into the Claus furnace, wherein said streams are injected such that the angle formed by the speed vectors of each of the streams is smaller than approximately 15.degree. when taken immediately after said streams emerge,(b) controlling the speed of injection of the gas stream comprising hydrogen sulphide and the speed of injection of the oxygen-enriched gas stream such that said speeds have a ratio between 0.8 and 1.2, and such that the furnace temperature is from 1000.degree. C. to 1800.degree. C.
