Abstract
A method and apparatus for eliminating COS and/or CSfrom a hydrocarbon-containing feed stream, and further eliminating HS from such feed stream or converting all sulfur species in such feed stream to HS and SOto allow for easy subsequent conversion of such HS and SOto elemental sulfur in a Claus reaction. The method comprises: (i) injecting water so that the feed stream contains greater than 10 vol % (water equivalent); (ii) passing the feed stream through catalyst means which hydrogenates COS and/or CSto HS; (iii) injecting Oso that the stoichiometric ratio of Oto HS is at least 0.5:1.0; (iv) passing the stream though a reaction zone having oxidation catalyst means which oxidizes HS to elemental sulfur or SO(depending on the amount of oxygen and water added); where the temperature of the reaction zone is above the elemental sulfur dew point.
