We have licensed our Direct Oxidation Technology for the removal of sulfur from reducing gas streams such a natural gas or landfill gas to SulfaTreat (Chesterfield, MO). , A Business Unit of M-I (a Smith/Schlumberger Company), SulfaTreat is the world leader in small scale sulfur removal. Our Direct Oxidation process catalytically converts hydrogen sulfide to elemental sulfur at 300-500˚F. The process was originally developed under DOE SBIR funding and then demonstrated at Whiting Petroleum’s Sable San Andreas Gas Plant with support from the DOE and GTI. SulfaTreat now offers the process worldwide, with engineering and fabrication carried out by Westfield Engineering of Houston.
