US Filter's Gas Technology Croup (USF/GTP) is currently introducing a new H 2 S removal process named Sulfur‐Rite TM . Sulfur‐Rite is specifically designed to remove small quantities of H 2 S (≤ 125 kg/day) from all types of gas streams. The Sulfur‐Rite process can remove H 2 Sfrom gas streams at any pressure. For non‐hydrocarbon gas streams the temperature is limited to approximately 115° and for hydrocarbon gas streams the temperature is limited to approximately 82°C. The non‐hazardous, environmentally friendly Sulfur‐Rite media converts H 2 S to iron pyrite (fool's gold). In addition to H 2 S, the Sulfur‐Rite process can remove approximately 50% of methyl and ethyl mercaptans. The spent media may be disposed of in a non‐hazardous landfill or made into compressed blocks for structural use or in some instances used as a soil supplement. The Sulfur‐Rite Equipment Packages are designed and supplied by USF/GTP. Single vessel and lead/lag dual vessel systems are available. This paper will discuss in detail the gas streams that can be treated, the equipment available, the advantage of Sulfur‐Rite over certain types of scavenger processes, and the disposal of the spent media.
