SULFATREAT/ Purification Solutions

SULFATREAT is the most widely used original product as it is the most highly rated scavenger on the market. It is an environmentally friendly solution as the granular material used to remove hydrogen sulphide (H2S) from natural gas streams is non-hazardous.
M-I SWACO has a Global Operation in over 1500 applications in over 20 countries and processes almost 3 trillion cubic feet of gas annually.


The global upstream and downstream energy, environmental and water treatment markets where removing concentrations of H2S as low as 1 ppm is a top priority.

M-I SWACO’s main domain is oil and gas but its applications extend to a much broader spectrum

  • Ammonia Plants
  • Asphalt Plants
  • Associated Sales Gas
  • Coal Gasification
  • Early Production Systems
  • Food Grade CO2
  • Gas Plants
  • Gas Storage
  • Geothermal
  • Instrument Gas
  • FPSO’s
  • Landfills
  • Liquid Sulfur Processing
  • Oil & Gas Field Vent Gas
  • Oil & Gas Fuel Gas
  • Oil Terminals & Shipping
  • Primary Sales Gas
  • Petrochemical Plants
  • Refinery
  • Waste & Sewage Gas
  • Waste Disposal Systems
  • Odor Control
  • Offshore Platforms


In many upstream and downstream gas gathering and production operations, as well as environmental and water treatment sites, high concentrations of H2S are generated which cannot be economically treated using liquid chemicals alone.
SULFATREAT offers various customised treatment systems to treat large volumes of sour gas using SULFATREAT and SULFATREAT Select products which selectively remove H2S in either dry or wet saturated gas through specially formulated products.

Using SULFATREAT solutions, we can treat gas for:

  • H2S removal
  • Hg removal
  • H2S & Hg (combined) removal


SULFATREAT is a cost-effective solution to removing H2S concentrations compared to other industry scavengers. Single-vessel units can reduce costs even further.
