SWAATS was developed to process sour water stripper gas by converting the ammonia and hydrogen sulfide to ammonium thiosulfate.  It can also be applied to

  • Process amine acid gas
  • Capture SO2 from oxidized Claus tail gas or an extraction process such as MECS’ SolvR™.
  • Provide backup (redundancy) for Claus
  • Remove H2S from sour hydrocarbon gas or CO2
