METHOD FOR PARTIALLY OXIDISING A GAS STREAM CONTAINING HYDROGEN SULPHIDE

摘要

A method for partially oxidising a gas stream containing hydrogen sulphide in a Claus furnace, wherein (a) the hydrogen sulphide-containing gas stream and an oxygen-enriched gas stream are injected into the Claus furnace at substantially parallel rates, (b) the injection rate of the hydrogen sulphidecontaining gas stream and the injection rate of the oxygen-enriched gas stream are controlled, (c) the oxygen in the oxygen-enriched gas stream is reacted with the hydrogen sulphide, and (d) a hydrogen sulphide-depleted and sulphurenriched gas stream is produced at the outlet of the Claus furnace.
