ABSTRACT:
The present invention provides a method for removing sulfur species from a gas stream without the use of a sulfur species removal process, such as an amine scrub. The sulfur species are removed by directly subjecting the gas stream to a sulfur recovery process, such as a Claus or sub-dewpoint Claus process at high pressure and moderate temperatures, wherein the sulfur recovery process comprises a catalyst which does not comprise activated carbon.
