Who is SulfaTreat?

A business unit of M-I SWACO
Today there are over 2,000 SulfaTreat installations worldwide in more than 20 countries.  Almost 4 trillion cubic feet of gas is processed by SulfaTreat annually.

Why Sulfatreat?

  1. Has minimum foot print [ 1/10 ]
  2. Highly Efficient [99.99%]
  3. Highly Effective
  4. Negligible pressure drop across SLFATREAT unit
  5. Does not require associated utilities to operated SULFATREAT UNIT
  6. No manpower is required to operate the process
  7. Low Capital Cost
  8. Low Operating Cost
  9. Negligible maintenance cost
  10. Robust product quality and the performance is not affected by fluctuation of H2S content
  11. Extremely safe to operate
  12. Environmental friendly. No H2S and emission in the atmosphere
  13. Able to remove mercury from the gas
  14. Classified and benchmarked by GRI [Gas Research Institute] research center as the best H2S removal process, among others.


Sulphur applications

The wasted byproduct [composite of Sulphur] is environmentally friendly, safe and has many applications.

  • Can be used as a sand stabilizer,
  • Can be used for road construction
  • Can be used as bricks.
  • Can be used as fertilizer

SulfaTreat Products

A range of absorbents for the removal of hydrogen sulphide and light mercaptans from natural gas and/or CO2 streams, water, air, geothermal vapours, landfill gas, biogas and light liquid hydrocarbons

Iron oxide based

The SulfaTreat Range

SulfaTreat
The original SulfaTreat product, rated “the best H2S scavenger” by the Gas Research Institute [ GRI ]

SulfaTreat-HP
For sweetening gas that is less than fully water saturated or for faster reaction speed with fully saturated gas

SulfaTreat-HP 410
For low pressure applications such as vent gas or odour control

SulfaTreat-XLP
Similar to the original SulfaTreat product but with up to 2.5x the bed life

Sulfatreat HC
For sweetening hydrocarbon liquids such as LPG, LNG, propane and diesel

 

The SELECT Range

SulfaTreat SELECT HP

  • Mixed metal oxide for the low temperature Desulphurisation of gas streams
  • Cu/Zn/MnO2; temperature 50-140 degF

SulfaTreat SELECT HC

  • Mixed metal oxide for low temperature desulphurization of light liquid hydrocarbons
  • Cu/Zn/MnO2: temperature 50-140 degF

SulfaTreat Ultra

  • High activity mixed metal oxide for the ultra purification of gas and liquid streams
  • Cu/Zn: temperature 50-400 degF

 SulfaTreat Chemistry

 

  • A dry granular media that selectively removes H2S and light mercaptans from vapour and liquid streams
  • FeXOY + H2S =======> FeS2 + H2O
  • Reliable and predictable results
    • Fixed bed process; consumption of media versus mass of H2S is consistent
    • Breakthrough of H2S, slow and manageable
    • Pressure drop, consistent over life of bed
  • Environmentally safe, new and used
    • Disposal in non-hazardous landfill most common
    • Has many non-disposal uses where permitted
    • Safe to handle, non-pyrophoric.

Disposal in landfill iron sulphide

  • Observe national waste disposal directives.
  • USA Environmental Protection Agency (EPA) test protocol cited in 40 CFR Subpart C (Section 261.20 through 261.24) reacted iron disulphide media is not listed as a hazardous waste in Subpart 261.30 to 261.33 of “Identification and Listing of Hazardous Wastes”.
  • European Union Directive 32001D0119 Reacted iron disulphide is considered a non hazardous waste under; 06 06 Wastes from the manufacture, formulation, supply and use of sulphur chemicals, sulphur chemical processes and desulphurisation processes. 06 06 03 Wastes containing sulphides

Environmental

The vast majority of reacted SulfaTreat (iron oxide based) is disposed in Class II non-hazardous landfills.

 

 

 

 

 

Alternate disposal iron disulphide

  • Used in road and building construction.
  • Used to help stabilize sand.
  • Recycled by kiln roasting.

Disposal of heavy metal media
