PROSERNAT Explores Boosting Sulphur Recovery with Sub-Dewpoint Processes Over the years, improvements to sub-dewpoint processes have allowed sulphur recoveries as high as 99.9% to be reached. More recently, the development of internally cooled catalytic reactors has also opened the door for sub-dewpoint operation in the Claus unit itself.

SweetSulf™: The High Pressure Redox Desulfurization Process SweetSulf™ Process Description Reaction Sour gas is contacted with an aqueous redox solution which extracts the H2S and converts it into solid elemental sulphur. Gas separation Treated gas, free of H2S, is separated from the redox solution. Solid separation Solid sulphur is filtered under pressure on a cartridge filter which can be regenerated on stream. Re-Oxidation The redox solution is depressurized and re-oxidized by contact with air.
