Sulfur Removal and Recovery

CrystaSulf

• Removes H₂S from any gas stream using a patented, liquid phase Claus reaction.
• Directly treats sour natural gas at pressure using a one-step hydrocarbon based treatment
• Brings the operational reliability of the Claus process to the medium scale sulfur removal market (0.1 to 25 tons per day)
• Has exceptional environmental characteristics

CrystaSulf Direct Oxidation

• CrystaSulf-DO is a current technology development initiative between CrystaTech, GTI and two public utilities.
• Extends the treating range of CrystaSulf into the core of the Claus market.
• Removes up to 250 tons per day of sulfur from any gas stream using a patented process.
• Places a direct oxidation (“DO”) unit in front of the CrystaSulf unit.
• Performs a bulk H₂S cut, removing up to 90% of the contaminant in a high pressure reactor
• CrystaSulf acts as a polishing unit, removing the remaining H₂S.
