Abstract
A method and apparatus for removing hydrogen sulfide from a molten sulfur stream containing hydrogen sulfide and hydrogen polysulfides by mixing the molten sulfur stream with a degassed molten sulfur stream in an eductor to form a mixture, contacting the mixture with a finely dispersed gaseous oxidant stream, separating hydrogen sulfide from the mixture and recovering molten sulfur having a reduced hydrogen sulfide content.
