SweetSulf™ Process Description.
Sour gas is contacted with an aqueous redox solution which extracts the H2S and convertsit into solid elemental sulphur.
Treated gas, free of H2S, is separated from the redox solution.
Solid sulphur is filtered under pressure on a cartridge filter which can be regenerated on stream.
The redox solution is depressurized and re-oxidized by contact with air.
