Abstract
A multistage oxygen-added catalytic partial oxidation process and apparatus for converting H2S in an acid gas stream to elemental sulfur and water are disclosed. Each staged addition of oxygen or air at the top of the catalyst bed and at points along the catalyst bed maintain oxygen-limited H2S catalytic partial oxidation conditions whereby incidental SO2 production is minimized.
