Expendable and Regenerable Sorbent Technologies for Sweetening Sour Gas Streams

We Work Closely With You to Engineer the Best Solution for Your Application

SulfaTrap™ sorbents effectively remove hydrogen sulfide (H2S), carbonyl sulfide (COS), thiols (e.g., methyl mercaptans, ethyl mercaptan, propyl mercaptan), thiophenes (e.g., tetrahydrothiophene) and disulfides to ensure the gas meets the sale gas spec and provide maximum protection to process equipment and catalyst systems that may be used to convert the gas as a feedstock into value-added chemicals (e.g., protecting the SMR catalysts used in hydrogen production). Our sorbents will be tailored to your needs with unique features including:

  • Moisture Tolerance

    SulfaTrap™ sorbents are tolerant to moisture and can handle completely dry or fully saturated gas

  • Highly Efficient

    SulfaTrap™ sorbents have a high removal efficiency for all sulfur species, reducing total sulfur concentration to <4 ppbv S

  • Operation Temperature

    SulfaTrap™ sorbents operate at near ambient temperature -20 to 450°C

  • High Capacity

    SulfaTrap™ sorbents have a high capacity, H2S capacity in excess of 35%-w S

  • Tolerance to Heavy Hydrocarbons

    Our materials are highly selective for sulfur compounds, and their performance will not be affected from the presence of olefinic, aliphatic and aromatic compounds

  • Safety

    SulfaTrap™ sorbents are easily disposable and are not flammable

  • Regeneration Capability

    SulfaTrap™ offers sorbents that can be regenerated by mild temperature swing

SulfaTrap offers full service engineering, design and construction services including modular fabrication, field services and material and process support.

SORBENTS FOR BULK DESULFURIZATION

 

 

The SulfaTrap™-R7 sorbent technology is designed for ultra-purification of natural gas, biogas, CO2 streams, associated gas and a wide range of hydrocarbon streams (ranging from LPG to natural gas liquids to diesel fuel). The SulfaTrap™ sorbents can remove H2S and all other organic sulfur compounds (such as mercaptans, sulfides, thiophenes) to very low concentrations (single digit ppbv levels if needed).

SulfaTrapTM offers products to treat natural gas, the ubiquitous energy source and feedstock for a wide range of chemicals.

Sulfur compounds in natural gas degrade process equipment and poison catalysts used in chemical synthesis processes.  In addition to naturally occurring sulfur, pipeline gas also contains organic sulfur odorants such as dimethyl sulfide (DMS), tertiary-butyl mercaptan (TBM) and tetrahydrothiophene (THT).  Sulfur content in the gas can change between wells, pipelines, and seasons. Heavy hydrocarbons and moisture further complicate the problem. SulfaTrap™ sorbents remove all naturally occurring sulfur compounds (H2S, COS), organo-sulfur odorants, di/sulfides, mercaptans, and thiophenes. Our sorbents reduce the sulfur concentration to ppbv levels to ensure maximum protection.
