Abstract
A process and apparatus for recovering sulphur from a hydrogen sulphide containing gas stream are disclosed. A gas stream containing hydrogen sulphide gas is passed into an apparatus having a first thermal-reaction-region and a first catalytic region and reacting a portion of the hydrogen sulphide gas to sulphur dioxide and water and reacting a further portion to form sulphur vapor and water vapor to form a resultant-gas-mixture of water vapor, sulphur vapor, sulphur dioxide and hydrogen sulphide and passing a portion to the first catalytic-region whereby at least a portion of the hydrogen sulphide is reacted in the presence of a catalyst to form further sulphur vapor and water vapor and condensing at least a portion of sulphur vapor to form liquid sulphur and passing at least a portion of the liquid sulphur to a sulphur pit.
