Abstract
A method for recovering sulfur from a sulfur-bearing process gas stream in which a process gas stream comprising HS and/or SOis contacted with a lean mixture of a lean UCSRP solution and a catalyst for promotion of a reaction between HS and SOin anon-UCSRP vessel at a temperature below which HS and SOreact, whereby at least a portion of the HS and/or SOis absorbed by the lean UCSRP solution, forming a rich mixture of a rich UCSRP solution and the catalyst. The rich mixture is introduced into a UCSRP vessel and heated to a reaction temperature greater than or equal to a melting temperature of sulfur, forming elemental sulfur and HO.
