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 each of the streams is injected at a speed of injection which is substantially parallel, (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 the speeds have a ratio between 0.8 and 1.2.
